Questions & Answers about Il aime faire du sport pour renforcer ses muscles.

Why is the phrase faire du sport used instead of jouer un sport or simply faire sport?

In French, many activities like sports are introduced with the verb faire, not jouer, except when you refer to specific ball games (e.g. jouer au football, jouer au tennis).

  • faire du sport treats “sport” as a general, uncountable activity (“to do some sport/exercise”).
  • You never say faire sport without an article, and jouer un sport is not idiomatic.
What is the function of du in faire du sport, and why is sport singular?

Here du = de + le is the partitive article, used to talk about an unspecified quantity of an uncountable or mass noun.

  • sport is singular because it’s treated as an abstract, mass concept (“some sport/exercise”), not as individual countable items.
  • You wouldn’t say faire des sports in everyday French; faire du sport covers the general idea of exercising.
How do you express purpose with pour + infinitive? Why pour renforcer ses muscles here?

When the subject of both verbs is the same, French uses pour + infinitive to express purpose (“in order to…”).
Example breakdown:

  • Il aime faire du sport → main action
  • pour renforcer ses muscles → why he does it

You cannot insert à or another preposition here; pour directly before the infinitive is the standard way to show intention.

Could I use afin de renforcer ses muscles instead of pour renforcer ses muscles?

Yes, you can. afin de + infinitive is more formal but has the same meaning (“in order to strengthen his muscles”).

  • pour + infinitive = everyday, neutral
  • afin de + infinitive = slightly more formal or written style
Why is the verb renforcer used rather than another verb like fortifier or augmenter?

renforcer means “to strengthen” or “to make stronger.” Other verbs are possible but carry subtle differences:

  • fortifier also means “to fortify,” often used for habits or defenses
  • augmenter means “to increase,” more general and could apply to quantity rather than strength

Here, renforcer ses muscles is the most idiomatic way to say “to build/strengthen one’s muscles.”

Why use ses muscles instead of les muscles or son muscle?
  • ses = “his” (plural) because you’re talking about all of his muscles.
  • les muscles would mean “the muscles” in a generic sense, not necessarily his.
  • son muscle (singular) would imply one specific muscle, which doesn’t fit the general idea of working out all muscles.
Could I say Il aime à faire du sport pour renforcer ses muscles instead of Il aime faire du sport…?

No. In modern French, aimer is followed directly by an infinitive without à.

  • Correct: Il aime faire…
  • Incorrect/archaic: Il aime à faire…

If you want to use à, you need a different verb (e.g. commencer à faire, apprendre à faire).

Is there a liaison or special pronunciation in faire du sport pour renforcer ses muscles?
  • faire du sport: no liaison between du and sport, so you pronounce it [fɛʁ dy spɔʁ].
  • sport pour: final t in sport is silent (next word starts with p, a consonant).
  • renforcer ses: you can link the r of renforcer with the s of ses as a slight liaison [ʁɑ̃.fɔʁ.sɛʁ sɛ myskl].
    Overall, pronounce naturally without forcing liaisons you’re unsure about.
