Learn French: Comment est-ce que tu lis ce texte flou ?

Flou means blurry, fuzzy, or out of focus. It is commonly used for physical things like eyesight, photos, or text, but it can also be used figuratively for vague concepts, plans, or memories (for example, une idée floue).

Why use est-ce que here instead of inversion (Comment lis-tu) ?

Comment est-ce que tu lis... is the standard, everyday way to ask a question in spoken French. Inversion (Comment lis-tu...) is more formal. At a B2 level, you should be comfortable with both, but the est-ce que structure is very natural for daily conversation.

How would I answer this question with 'I can hardly read it' using ne... guère from our current lesson?

You could answer Je ne le lis guère or Je ne peux guère le lire. Remember that guère completely replaces pas in the negative structure. Because ne... guère is a literary and formal structure, using it elevates the tone of your sentence compared to the more common everyday phrasing Je peux à peine le lire (I can barely read it).

If I want to reply 'I read it with my glasses,' where does the pronoun go?
