Formal Sequence: Subsequently & Thereafter
Grammar Rule in 30 Seconds
Use 'subsequently' and 'thereafter' to link events chronologically in formal writing, replacing basic words like 'then' or 'after that'.
- Use 'subsequently' for events following another in a series. Example: 'He resigned and subsequently left the country.'
- Use 'thereafter' to mean 'from that time forward'. Example: 'The policy changed; thereafter, profits rose.'
- Place 'subsequently' before the verb or at the start of a clause with a comma.
Overview
Good English is clear. Use these words for time and order.
Both words mean after. They show why things happen.
These words make your writing better. This guide helps you.

When To Use It
- To detail a process:
The cell culture was incubated for 24 hours at 37°C. Subsequently, microscopic analysis revealed significant cellular proliferation.(Direct follow-up in a procedure) - To explain historical causality:
The economic downturn of the 1930s led to widespread social unrest. Subsequently, many governments implemented drastic fiscal reforms.(Reforms were a direct response to unrest) - To trace intellectual lineage:
Descartes published Discourse on the Method in 1637; thereafter, rationalism gained significant traction in philosophical thought.(The influence of rationalism began from that point and continued).
- In a project report:
The software update was successfully deployed last quarter. Subsequently, customer support calls related to this module decreased by 18%.(Direct positive outcome) - In a legal contract:
Payment is due on the 1st of each month. Thereafter, a late penalty of 5% will be applied to the outstanding balance.(The penalty begins from a specific point). - In policy documentation:
Employees are required to complete mandatory cybersecurity training annually. Thereafter, access to sensitive company data will be granted.(Access is conditional upon completion).
- In a court judgment:

Common Mistakes
- Incorrect Use of
subsequentlyfor duration:She moved to Canada in 2020, and subsequently, she lived there for five years.(The living for five years is a duration, not a direct, immediate, and singular consequence. Correct:...and thereafter, she lived there for five years.) - Incorrect Use of
thereafterfor direct consequence:The unexpected system crash occurred. Thereafter, all unsaved data was lost.(The data loss is a direct consequence of the crash, not an ongoing state from that point. Correct:...subsequently, all unsaved data was lost.) - Correction Strategy: Always ask yourself: Is the second event a direct, immediate outcome, or does it describe a state or action that began at that point and continued? The answer guides your choice.
- Incorrect (casual):
I finished my coffee; subsequently, I went to the gym.(Too formal for casual speech. Natural:I finished my coffee, then I went to the gym.) - Incorrect (casual):
Got my degree last year, and thereafter, I've been traveling.(Overly formal. Natural:Got my degree last year, and since then, I've been traveling.) - Correction Strategy: Reserve
subsequentlyandthereafterfor academic, professional, legal, or highly formal journalistic contexts. For informal settings, opt for simpler temporal connectors.
- Incorrect:
The initial analysis was completed subsequently the report was drafted. - Correct:
The initial analysis was completed; subsequently, the report was drafted. - Correction Strategy: Remember the comma acts as a brief pause, separating the adverbial phrase from the main clause, especially when the adverb functions as a sentence connector.
subsequently or thereafter alongside other phrases that convey the same temporal meaning can lead to wordiness and clumsy prose.- Incorrect:
After the meeting concluded, subsequently, the decisions were disseminated.(Redundant. Choose one:After the meeting concluded, the decisions were disseminated.ORThe meeting concluded; subsequently, the decisions were disseminated.) - Correction Strategy: Ensure conciseness by avoiding phrases that repeat the temporal information already conveyed by the adverb.
The experiment produced conflicting results; consequently, the hypothesis was disproven.(consequentlyhighlights the logical conclusion.)The experiment produced conflicting results; subsequently, the researchers redesigned the study.(subsequentlyhighlights the next temporal action, which happens to be a consequence.)- Correction Strategy: Distinguish between a sequence of events (temporal) and a conclusion drawn from premises (logical).
Subsequentlybridges both;thereafteris purely temporal.
Real Conversations
Understanding how subsequently and thereafter are employed in authentic communication, particularly in formal settings, is crucial for effective usage. While generally absent from casual dialogue, these adverbs are integral to clarity and precision in academic, professional, and legal discourse, often in spoken contexts where formality is expected.
1. Academic Presentations and Lectures
When presenting research, outlining theories, or discussing methodologies, speakers often use these adverbs to maintain a clear narrative and logical flow.
- Our pilot study indicated a novel correlation; subsequently, we expanded our sample size to confirm the findings. (Explaining a methodological progression)
- The theory of relativity was proposed by Einstein in 1905. Thereafter, our understanding of space and time was fundamentally altered. (Marking a historical turning point and its lasting impact)
2. Business Meetings and Corporate Reports
In board meetings, project updates, or when delivering formal presentations, these adverbs help to articulate processes, outcomes, and future directives with professional gravitas.
- The merger negotiations concluded successfully last month. Subsequently, the integration of operational teams began in earnest. (Reporting a direct follow-up action)
- Upon ratification by the shareholders, the new dividend policy will take effect. Thereafter, quarterly dividends will be distributed directly to registered shareholders. (Outlining an ongoing financial practice)
3. Legal Proceedings and Testimony
In legal contexts, where precision is paramount, subsequently and thereafter are used to establish undeniable sequences of events or lasting conditions, whether in written affidavits or oral testimony.
- The suspect was apprehended at the scene. Subsequently, he was read his Miranda rights. (Detailing a precise legal sequence)
- She obtained her professional license in 2005. Thereafter, she practiced law continuously until her retirement. (Establishing a continuous professional activity from a specific date)
4. Formal Speeches and Public Addresses
Politicians, diplomats, and other public figures employ these adverbs in formal addresses to structure their arguments, recount historical events, or project future policy implications with authority.
- The treaty was signed by all member states. Subsequently, measures for international cooperation were significantly strengthened. (Attributing a positive outcome to a specific event)
- The foundational principles were laid down by our predecessors. Thereafter, each generation has been tasked with upholding and advancing these values. (Referring to an enduring legacy and continuing responsibility)
These examples illustrate that while subsequently and thereafter are formal, their application in spoken English occurs naturally within contexts that demand a high degree of precision, intellectual rigor, and an authoritative tone. They contribute to a speaker's ability to convey complex information clearly and persuasively, distinguishing advanced communication from everyday banter.
Quick FAQ
subsequently and thereafter be used interchangeably?No. While both indicate sequence, subsequently implies a direct consequence or close temporal succession, often with a causal link. Thereafter signifies a continuing state, action, or pattern that begins from a specific point in time and extends indefinitely or for a defined duration. Confusing them is a common error that can alter the intended meaning of your sentence.
For informal contexts, you would typically use then, after that, next, or simply restructure your sentence with and. For thereafter's sense of continuity, since then or from that point on are good informal substitutes.
subsequently or thereafter?When they appear at the beginning of a clause or sentence, a comma is almost always required (e.g., Subsequently, the decision was made. or The report was clear; thereafter, no further questions arose.). When they are embedded within a clause (medial position), particularly before the main verb or after an auxiliary verb, a comma is generally not used (e.g., The project was subsequently approved.).
Not typically. They are characteristic of formal written English, including academic papers, legal documents, and official reports. You might hear them in very formal speeches, presentations, or news broadcasts, but they sound unnatural in casual conversation.
subsequently mean simply later or at a later time?Yes, it can mean later, but it carries the added connotation of the event being a logical or direct follow-up. While it functions temporally, it also often implies a stronger relationship than a simple later or afterwards.
Think of Subsequently for Sequence/conSequence (a direct follow-up) and Thereafter for Time/conTinuation (from that time onwards). This emphasizes the core distinction in their functions.
subsequently and thereafter differ from afterwards?Afterwards is a general temporal adverb meaning at a later time. It is less formal than subsequently and simply indicates chronological order without the strong implications of direct consequence or ongoing duration. While afterwards can sometimes replace subsequently for pure temporal meaning, it lacks the formality and the strong causal or logical connection. Thereafter has a more specific meaning of

FAQ (8)
It is rare. Usually, 'subsequently' is placed before the verb or at the start of a clause. 'Thereafter' is much more common at the end of a sentence.
No. 'Subsequently' means 'afterwards' (time). 'Consequently' means 'as a result' (cause).
Always use a comma after it: 'Subsequently, the project was cancelled.'
It depends on the culture. In a law firm or bank, it's fine. In a tech startup, it might sound a bit stiff.
Yes, 'subsequent to' is a formal prepositional phrase. 'Subsequent to the meeting, we had lunch.'
Not necessarily. In legal contracts, it can refer to the future: 'The fee shall be $100 in 2025 and $150 thereafter.'
The opposite is 'heretofore' or 'prior to that', though these are even more formal.
Because science requires a precise description of steps in an experiment, and 'subsequently' provides that without sounding repetitive.

Posteriormente / A partir de entonces
Spanish often uses 'luego' which is much more common than 'subsequently' is in English.
Par la suite / Ultérieurement
French speakers often over-rely on 'après' when they should use these more formal terms in English.
Anschließend / Danach
German word order (V2) means these adverbs often trigger a verb-subject inversion, which doesn't happen in English.
その後 (Sono go) / 以後 (Igo)
Japanese connectors often appear at the very start of a sentence with a specific particle like 'wa' or 'ni'.
بعد ذلك (Ba'da dhalika) / من ثم (Min thamma)
Arabic often uses 'wa' (and) to link sequences where English would use a more specific adverb.
随后 (Suìhòu) / 此后 (Cǐhòu)
Chinese does not require the same punctuation (semicolons) to link these clauses.
