Avoir envie de versus envier:
avoir envie de : to want/to feel like
envier: to envy
If you say J'ai envie de toi instead of Je t'envie, you're saying you want someone sexually instead of saying I envy you. Oups.
J'ai envie d'une glace: I feel like having an ice-cream. This is ok.
Qu'est-ce que tu fais cette nuit? What's wrong with that one, you might think. La nuit in France is from 11pm/12am. In English, we always use tonight for the evening. Asking somebody what s/he is doing cette nuit might get you into an awkward conversation.
Say: Qu'est-ce que tu fais ce soir? Unless you really mean cette nuit...
Baiser versus baisser
Just make sure you pronounce these verbs properly. You don't want to say the wrong one.
's' is like a 'z'
'ss' is a strong 's' like the one in 'Sail', not a 'z' sound.
Je t'aime versus Je t'aime bien:
Love:
Je t'aime: I love you
Friendship:
Je t'aime bien: I like you
Je l'aime bien: I like him/her
Je les aime bien: I like them
