Those two words do not exactly go together.
Je (I) goes with ai (have) to make J'ai (I have)
Avez is a different conjugation to suit vous (You to a person in authority, or You in plural)
So if you heard J'avez in a sentence before, It must have started with Vous j'avez...
French is confusing.
Sorry for my first answer.
"J' avez" is not correct French grammar. The correct form would be "j'avais," which means "I had" in English.
"Ou avez-vous appris le français?" means "Where did you learn French?" in English.
"Where did you meet your spouse?"
"Vous avez toute la classe" means "You have all the class" in English. It is a compliment used to describe someone who exudes elegance, sophistication, and style in their demeanor or behavior.
"avez" is the second person plural form of the verb "avoir" in French, which means "to have." It is not inherently masculine or feminine, as verbs do not have gender.
"J' avez" is not correct French grammar. The correct form would be "j'avais," which means "I had" in English.
Do you have? Avez-vous une voiture? Do you have a car?
you have
"Est-ce que vous avez ..." means "do you have..." in French.
"How old are you?"
De quoi avez-vous besoin ? means What do you need now?
ou avez-vous rencontre votre conjoint means: or did you meet your spouse.
It means : You lost
"You were a dream"
un hibou (n 'x' when singular,only when plural) is an owl in French. 'Avez-vous' is a question meaning 'do you have?', so 'avez-vous mon hibou' means 'do you have my owl' in English.
You disappeared yesterday
"vous avez assez yeux Mme" reads litterally "you have enough eyes madam". (Makes no sense to me).
