"I am eating pasta."
Translation:Je mange des pâtes.
In English, to mean that an action is in progress at the time you speak, you use the continuous verbal form, ie verb BE + action verb in the gerund form (-ing).
o he is eating means he currently eats
In French, this verbal form does not exist (directly translated “il est mangeant” is incorrect). Therefore, you can translate either “il mange” or “il est en train de manger”, where the construction verb être + en train de + infinitive correctly expresses the English continuous form.
Unlike English, French has extensive conjugations.
The infinitive form of this verb is "manger". When you conjugate it, its ending changes according to the personal pronoun used: je mange, tu manges, il/elle/on mange, nous mangeons, vous mangez, ils/elles mangent.
"I am eating" is a continuous present; this verbal form does not exist in French so the continuous present and the simple present tenses should be translated to the French present.
I am eating = I eat = je mange.
