Guardar lo mejor para el final: El Principio de Peso Final
natural y claro.
Grammar Rule in 30 Seconds
English sentences prefer 'heavy' or long information at the end to make them easier to read and understand.
- Move long subjects to the end using 'It' as a placeholder: 'It is clear that he lied.'
- Place longer objects after shorter ones: 'I gave the book to the girl with the red hat.'
- Avoid 'top-heavy' sentences where the subject is much longer than the verb phrase.
Overview
pesadas o poco naturales? Como hablantes de español, estamos acostumbrados a una gran flexibilidad sintáctica. Podemos mover el sujeto al final, omitirlo por completo o crear frases subordinadas extensas antes de llegar al verbo principal sin perder la claridad.dada (conceptos que ya se han mencionado o que son fáciles de entender) y transitamos hacia la información nueva (el mensaje central o los detalles novedosos). El final de la oración es la posición de mayor énfasis natural, lo que la convierte en el lugar ideal para esta información pesada.Que el equipo no haya llegado a tiempo me preocupa, donde el sujeto es toda una frase larga. En inglés, aunque
That the team didn't arrive on time worries me es gramaticalmente posible, suena poco natural y procesalmente pesado. El inglés prefiere usar un sujeto vacío (it) para empujar la información pesada al final: It worries me that the team didn't arrive on time.Que decidas irte ahora es triste. | Se evitan al inicio:

Meanings
The End-Weight Principle is a stylistic tendency in English where longer, more complex structures (phrases or clauses) are placed at the end of a sentence to improve processing and flow.
Extraposition of Subject
Moving a long clausal subject to the end and replacing it with 'it'.
“It is important that you arrive on time.”
“It bothered me that she didn't call.”
Dative Shift / Object Ordering
Ordering direct and indirect objects so the longer one comes last.
“I sent a letter to my cousin who lives in Australia.”
“She gave the man who was waiting outside a small gift.”
Heavy NP Shift
Moving a very long direct object to the end of the sentence, after an adverbial.
“He confessed to the priest all the sins he had committed over the years.”
“She explained to the students the importance of the upcoming exam.”

Identifica las Partes 'Pesadas'
Prioritize placing these later in the sentence for easier processing.
Smart Tips
Stop and try starting with 'It is...' instead. It will almost always sound more natural.
Use 'It is argued that' or 'It has been suggested that' to introduce sources. It follows end-weight and sounds objective.
Check which one is longer. Put the longer one at the very end.
Always use 'It' as a placeholder if you have a clausal subject.
Pronunciación
Dummy 'It' Stress
The word 'It' at the beginning of these sentences is almost never stressed. It is pronounced quickly as /ɪt/.
End-Focus Intonation
The pitch of your voice usually drops at the end of the 'heavy' part, which is where the most important information sits.
The Slide
It is certain that they will ↘️ win.
Conveys certainty and completion of the thought.
Memorízalo
Mnemotecnia
Heavy goes Home: Long parts of the sentence want to go 'home' to the end.
Asociación visual
Imagine a seesaw. If a giant (long phrase) sits at the front, the seesaw crashes. If the giant sits at the back, it stays balanced.
Rhyme
If the subject is long and brings a fright, move it to the end and make it right.
Story
A little word named 'It' was a hero. He saw a giant, heavy sentence part trying to climb onto the subject's chair. 'It' said, 'I'll sit here for you! You go relax at the end of the sentence.'
Word Web
Desafío
Look at a news article. Find three sentences that start with 'It is...' and try to rewrite them with the long part at the beginning. Notice how much harder they are to read!
Notas culturales
British English often uses end-weight in formal correspondence to maintain a polite, indirect distance. 'It would be appreciated if...'
In US universities, students are taught to avoid 'wordiness,' but the End-Weight principle is still encouraged to keep the 'action' (the verb) near the start of the sentence.
Legal documents use 'Heavy NP Shift' constantly to ensure that long lists of conditions don't interrupt the main verb of a contract.
The End-Weight principle has been a feature of Germanic languages for over a millennium, evolving as English shifted from a more flexible word order to a strict SVO structure.

Preguntas frecuentes (8)
No, it is not grammatically wrong, but it is stylistically 'heavy.' Native speakers avoid it because it makes the sentence harder to process.
No. In the End-Weight principle, only `It` works as a dummy subject. You cannot say '*This is true that he left.'
Usually no. If the subject is just one or two words (e.g., 'He is nice'), we don't move it. End-weight is for 'heavy' parts.
Typically, any phrase with more than 5-7 words, or any clause starting with `that`, `to`, `whether`, or `if`.
No, it's very common in speaking too! We naturally say 'It's funny that...' rather than 'That... is funny.'
End-weight is about the *length* of the words. End-focus is about putting the *newest* or *most important* info at the end.
It's most common with the verb `to be` and adjectives, or verbs of emotion/perception like `bother`, `seem`, `appear`, and `surprise`.
Because the word `It` doesn't actually refer to anything. It's just a 'placeholder' to keep the subject position filled.

Expositions-es
German verb-second (V2) rules make the placement of 'Es' more restricted.
Topic-Comment structure
The most important/heavy part (the verb) is always last in Japanese.
VSO order
The subject naturally follows the verb, so no 'extraposition' is needed.
Topic-prominent structure
Chinese is comfortable with very long 'topics' at the start of a sentence.
