John, fais attention aujourd'hui.
the eyes = les yeux But be careful : an eye = un œil
My love! be careful.
That only means "hello you're careful" :) In French.
attention, same as english, but careful with pronunciation.
The verb be in french is : être However, be careful using it, because if you say I'm cold in English , you cannot say je suis froid . You should say j'ai froid ( you have to use the verb to have). So, be careful with translation.
vendu(e) (be careful 'soldes' in French means sales - cut priced - which has been known to create misunderstandings!)
'faites gaffe' in informal French for 'be careful / take extra care'
