Explanation at your level:
You use swore to talk about the past. If you promised to do something yesterday, you say: 'I swore to do it.' It is a strong promise.
When you tell a story, you might say, 'He swore he was telling the truth.' It means he promised very seriously. Also, if someone is very angry, they might use bad words. We say, 'He swore at me.'
Swore is the past form of 'swear'. It is used in two ways. First, for promises: 'She swore to keep the secret.' Second, for bad language: 'He swore when he dropped his phone.' It is important to look at the context to know which meaning is intended.
In B2 English, you will see swore used in formal settings like courtrooms ('He swore under oath') or in casual descriptions of behavior. It conveys a sense of intensity, whether that intensity is found in a commitment or in an outburst of anger.
At the C1 level, swore often appears in literary contexts to denote a character's internal resolve. 'He swore a silent vow to himself.' It captures the weight of a decision. In academic writing, you might see it in historical analysis regarding oaths of allegiance or feudal contracts.
Mastery of swore involves understanding the nuance of 'oath-taking' as a cultural and historical construct. It is deeply embedded in legal, religious, and social history. Whether used to describe a binding covenant or a breach of social etiquette, the word carries a heavy, almost archaic weight that speakers use to emphasize the gravity of a past action.

Hey there! Let's talk about swore. It is the past tense of the verb swear. You will mostly use this word in two very different ways.
First, it means you made a solemn promise. Think of a knight in a movie who 'swore' to protect the kingdom. It implies a deep level of commitment.
Second, it refers to using profane language. If someone was angry and 'swore' at someone else, they used words that are considered rude or inappropriate. Context is everything here!
The word swore comes from the Old English word swerian. It has deep Germanic roots, related to the Old Saxon swerian and Old High German swerien.
Originally, it was deeply tied to the idea of taking an oath before a deity. In ancient times, 'swearing' was a legal act that carried heavy consequences if the promise was broken.
Over centuries, the meaning branched out. By the 14th century, it began to be associated with 'cursing' because people would often invoke sacred names in anger, which was seen as taking the Lord's name in vain.
When using swore, you usually follow it with a 'that' clause. For example, 'She swore that she was innocent.' This shows the content of the promise.
In the context of bad language, we often say someone 'swore at' someone else. This preposition 'at' is crucial to indicate the target of the anger.
It is a common verb in storytelling. Whether in a legal thriller or a casual conversation about a disagreement, swore helps set the emotional stakes of the narrative.
1. Swear blind: To insist very strongly that something is true. 'He swore blind that he didn't eat the cake.'
2. Swear on a stack of Bibles: To make a very serious, solemn oath. 'She swore on a stack of Bibles that she was telling the truth.'
3. Swear like a trooper: To use a lot of bad language. 'He was so frustrated that he swore like a trooper.'
4. Swear off: To promise to stop doing something, usually a bad habit. 'I have sworn off sugar for the month.'
5. Swear by: To have great confidence in something. 'I swear by this brand of coffee.'
Swore is an irregular verb. The pattern is swear (present), swore (past), and sworn (past participle).
Pronunciation: In US English, it sounds like /swɔːr/. In UK English, it is often /swɔː/. It rhymes with door, floor, more, and roar.
Remember that it is a transitive verb when used with an object (e.g., 'He swore an oath'), but it can also be used intransitively when talking about cursing (e.g., 'Please don't swear').
