Overview
let them et let they est une étape cruciale pour franchir le cap du niveau intermédiaire en anglais. Si tu as déjà eu un doute au moment de choisir entre ces deux formes, rassure-toi : c'est l'une des erreurs les plus fréquentes chez les francophones. Pourquoi ?let, on utilise toujours le pronom objet. Let them est donc la seule forme correcte, tandis que let they est une erreur grammaticale majeure.let est ce qu'on appelle un verbe de permission ou un verbe causatif. Il établit un pont entre une autorité (le sujet) et une action effectuée par quelqu'un d'autre (l'objet).them l'emporte sur they et comment utiliser cette structure pour exprimer la permission, la suggestion ou même l'acceptation avec l'aisance d'un natif.let them, il faut d'abord regarder la nature du verbe let. En français, nous le traduisons généralement par « laisser » ou « permettre ». C'est un verbe transitif, ce qui signifie qu'il a besoin d'un complément d'objet direct (COD) pour avoir un sens complet.I see them.(Je les vois.)- Tu ne dirais jamais
I see they, n'est-ce pas ? C'est exactement la même logique aveclet.
let est qu'il appartient à la catégorie des verbes causatifs. En anglais, ces verbes indiquent qu'une personne cause ou permet une action réalisée par une autre personne. La structure est la suivante :Subject + let + Object + Bare Infinitiveto. C'est là que beaucoup de francophones trébuchent. En français, on dit « Laisse-les partir » ou « Permets-leur de partir ». En anglais, on retire le to.- Français : Je les laisse (objet) + partir (infinitif).
- Anglais :
I let them(objet) +go(infinitif sansto).
let they vient souvent d'une confusion mentale avec la proposition subordonnée française : « Laisse qu'ils partent ». Dans cette phrase française, « ils » est le sujet du verbe « partent ». Mais en anglais, la structure avec let ne permet pas de subordonnée avec that.them.let est un verbe irrégulier dont la forme reste identique au présent, au passé et au participe passé (let, let, let).

Yes, the verb `let` conjugates like any other verb. 'He `lets` them play' or 'She `let` them play' (past tense). The pronoun `them` stays the same.
`Let` is informal and uses a base verb (`let them go`). `Allow` is formal and uses 'to' (`allow them to go`).
