Questions & Answers about Tu sens le navire bouger, n'est-ce pas ?
Why do we use the infinitive bouger instead of an '-ing' equivalent like bougeant?
In French, when you use a verb of perception like sentir (to feel), voir (to see), or entendre (to hear) followed by an action, that second action must be in the infinitive. While English says 'feel the ship moving', French expresses this as 'feel the ship to move' (sens le navire bouger).
Why is it sens and not te sens here?
If I wanted to say 'You feel it moving,' where would the pronoun 'it' go?
The direct object pronoun le (it) would go right before the main verb of perception (sens), not before the infinitive. You would say Tu le sens bouger.
Does n'est-ce pas change depending on the verb in the sentence?
No, n'est-ce pas is a fixed tag question. While English changes the tag to match the sentence ('don't you?', 'aren't we?', 'did they?'), French simply sticks n'est-ce pas at the end of the statement to ask for confirmation, meaning 'right?' or 'isn't that so?'.
