Questions about "le passé."
I know "I live in Paris. = J'habite à Paris."
"I lived in Paris," which on below is correct?
"J'ai habité à Paris." ou "J'habitai à Paris."
You loved me, "Tu as m'aimé." ou "Tu m'aimas." ?
Le passé is so complicated for me. >___<
Passé composé : J'ai habité à Paris. / Tu m'as aimé. (Pronoun m' proceeds the conjugated verb "avoir".)
Imparfait : J'habitais à Paris. / Tu m'aimais. (Pay attention to the spelling!)
Both tenses take place in the past but they aren't interchangeable.
Passé composé is used for : 1. a completed action in the past 2. an event that happened a single or countable number of times. 3. a new event at a precise moment. 4. an interruption.
Imparfait is used for : 1. an uncompleted action in the past. 2. something that happens habitually or is uncountable. 3. an ongoing event. 4. the background description.
This is not easy to get a feel for and just takes practice!
One final note: To say that you have lived in Paris since a certain year, the present tense is actually used in conjunction with "depuis."
Like this: J'habite à Paris depuis 2015. = I've been living in Paris since 2015.
J'apprends le français depuis un an. = I've been learning French for one year.
It depends on the situation you're using it in. Generally, the imparfait is used to describe what's going on in the background. Details like: what a person is wearing, what day it is, and what kind of weather it is outside. The passé composé is used to describe the main action or event.
I hope this helps!
