"My belt is big."
Translation:Ma ceinture est grosse.
for a belt, "grosse" means thick and wide.
grande would mean long.
So big is gros not grand? I know the gender is masculine in my question, it is only easier for me because of my keyboard.
gros is a matter of volume.
in the case of a belt, "grande" would mean that it is long
If grande would mean long and grosse is larger all around, isn't "grande" the meaning the sentence was conveying? For a belt to be big on a person, it would have to be too long in length. So based on previous information the correct word here should be grande, or at least both should be accepted.
The original sentence was written in French and reads "ma ceinture est grosse". Une grosse ceinture has a wide and thick band, and the buckle is large. Overall, it means that it is "voluminous" (the exact meaning of "gros/grosse").
Mon is a personal possessive pronoun referring to a masculine subject Ma refers to a feminine subject. It has nothing to do with your gender, so an apple , la pomme, is feminine to everyone because it has la instead of le.
Mon is used with masculine objects and ma with feminine objects (starting with a consonant).
if the object is feminine and starts with a vowel or a non-aspirate H, "ma" is changed to "mon":
mon amie - mon habitude
This link says 'belt' can be masculine, ceinturon. Is this true?
Yes, une ceinture and un ceinturon. The former is generic and the latter is more technical, ie "une ceinture" with professional features, for example.
Why can I say 'ma ceinture est grosse' but not 'la ceinture est grosse'?
Because the original sentence contains a possessive, that you cannot translate by an article.
gross is not a French word.
gros is for masculine nouns (singular and plural)
grosse is for feminine singular nouns; plural: grosses
"grand" means long, large (object) or tall (people) or great (a great man = un grand homme)
"gros" means voluminous (object) or fat (people)
Just so you know that the FR "large" refers to the width of something, not its length.
I never know when to use "gros/grosse". I've never been able to understand. Please Help!
