French Phrase
Je l'ai oublié chez moi.
Meaning
This phrase literally translates to 'I it have forgotten at my home.' It's used to express that you left something behind at your residence. The 'l'' is a direct object pronoun referring to 'it' or 'him/her' (depending on context, but usually 'it' when forgetting an object).
When to use
You would use this phrase when you realize you don't have an item with you because you left it at your house or apartment. It's a common excuse for not having something required, like a document, a key, or a specific item for an activity.
✦Grammar Breakdown
Jel'ai oubliéchez moi
Je (I)
This is the first-person singular subject pronoun, meaning 'I'. It's always used before the verb in French sentences.
l' (it/him/her)
This is a direct object pronoun. It replaces a noun that is the direct object of the verb. Here, 'l'' stands for 'le' or 'la' (it), and it elides before a vowel sound ('ai').
ai oublié (forgot)
This is the passé composé (past tense) of the verb 'oublier' (to forget). It's formed with the auxiliary verb 'avoir' (ai) and the past participle 'oublié'. Note that the past participle 'oublié' does not agree with the direct object 'l'' when 'avoir' is the auxiliary, unless the direct object precedes the verb, which it does here. However, 'l'' is singular, so 'oublié' remains unchanged.
chez moi (at my home/place)
This is an idiomatic expression meaning 'at my house' or 'at my place'. 'Chez' is a preposition that indicates location at someone's home or establishment, and 'moi' is the stressed pronoun for 'I'.

✕Common Mistakes
J'ai oublié à la maison.
While 'à la maison' means 'at home', 'chez moi' is more natural and idiomatic when referring to 'my home' specifically, especially when you're talking about forgetting something there. Also, the direct object pronoun 'l'' is missing.
J'ai oublié chez moi.
This is grammatically incorrect because 'oublier' (to forget) usually takes a direct object. You need the pronoun 'l'' (it) before the verb to refer to the forgotten item.
Je l'ai oublié à ma maison.
While understandable, 'chez moi' is the standard and most natural way to say 'at my house' or 'at my place' in French. 'À ma maison' sounds less idiomatic.

Cultural Tip
The use of 'chez' in French is very common and versatile. It literally means 'at the home of' or 'at the place of'. So, 'chez moi' means 'at my place/home', 'chez toi' means 'at your place', 'chez le médecin' means 'at the doctor's'. It's a key idiomatic expression that distinguishes French from more literal translations like 'à la maison'. Mastering 'chez' will make your French sound much more natural.
