Quand il fait froid, elle garde son foulard et ses chaussons même dans la cuisine.

In weather expressions, French very often uses faire:

• il fait froid = it is cold
• il fait chaud = it is hot
• il fait beau = the weather is nice

So il fait froid is the normal way to talk about cold weather or a cold वातावरण.

Il est froid usually describes a person, object, or thing as being cold, not the general weather:

• Le café est froid. = The coffee is cold.
• Il est froid. = He/it is cold.

Here, since the sentence is talking about the weather, il fait froid is the natural choice.

Here, quand means when:

• Quand il fait froid = When it’s cold

In many contexts, quand can also feel like whenever, especially when it describes a habitual situation:

• Quand il pleut, je reste chez moi. = When/Whenever it rains, I stay home.

In this sentence, it suggests a general habit: whenever it is cold, she keeps her scarf and slippers on.

French often uses the present tense to describe general habits or repeated situations, just like English can:

• Quand il fait froid, elle garde...
  = When it’s cold, she keeps...

This is not necessarily happening right now. It can describe what she usually does in that situation.

So the present tense here is a habitual present.

Not exactly. Garder basically means to keep.

So elle garde son foulard et ses chaussons literally means:

• she keeps her scarf and her slippers

In natural English, that often becomes:

• she keeps her scarf and slippers on

French uses garder when the idea is that she continues wearing them instead of taking them off.

If you just wanted to say she is wearing, French would more often use porter:

• Elle porte un foulard. = She is wearing a scarf.

So garde emphasizes that she keeps them on.

Because the possessive adjective must agree with the thing owned, not with the owner.

Here the owner is elle = she/her, but French does not choose son/sa/ses based on the owner’s gender. It chooses them based on the noun:

• foulard is singular masculine → son foulard
• chaussons is plural → ses chaussons

Compare:

• son foulard = her scarf
• sa veste = her jacket
• ses chaussures = her shoes

So son does not mean the owner is male. It can mean his or her depending on context.

Because foulard is a masculine noun:

• un foulard

So the possessive must be masculine singular too:

• son foulard

French grammar cares about the noun’s gender, not the real-world gender of the person who owns it.

Both can be translated as scarf, but they are not always the same.

• un foulard often suggests a lighter scarf, sometimes decorative, sometimes made of silk or thin fabric
• une écharpe usually suggests a warmer scarf worn around the neck for cold weather

In real life, usage can overlap, and context matters. In this sentence, foulard may simply refer to a scarf she keeps on when it is cold. A learner should just know that foulard is a normal French word for a type of scarf.

Chaussons usually means slippers or soft indoor footwear.

So:

• ses chaussons = her slippers

French often uses chaussons for the comfortable shoes people wear inside the house.

French often puts this kind of extra emphasis at the end:

• même dans la cuisine = even in the kitchen

The main idea comes first:

• Quand il fait froid, elle garde son foulard et ses chaussons...

Then the sentence adds the surprising detail:

• ...même dans la cuisine.

This placement makes the ending feel emphatic, a bit like:

• She even keeps them on in the kitchen.

Because dans means in/inside, which is what French normally uses for being inside a room:

• dans la cuisine = in the kitchen
• dans la chambre = in the bedroom

À is used in many other location expressions, but for a room you are physically inside, dans is the usual choice.

A careful approximate pronunciation is:

Kahn eel fay frwah, ell gard son foo-lar ay say show-son mem dahn la kwee-zeen.

A few useful notes:

• Quand sounds roughly like kahn
• il fait sounds like eel fay
• froid sounds like frwah
• foulard has a silent final d
• ses sounds like say
• même sounds like mem
• dans has a nasal vowel, so it is not pronounced like English dan
• cuisine sounds like kwee-zeen

In natural speech, French will sound smoother and more connected than this spelling suggests.

Yes. A few close alternatives are possible, depending on nuance:

• Quand il fait froid, elle porte encore son foulard et ses chaussons, même dans la cuisine.
  This stresses that she is still wearing them.

• Lorsqu’il fait froid, elle garde son foulard et ses chaussons même dans la cuisine.
  Lorsqu’ is a slightly more formal version of quand.

• Par temps froid, elle garde son foulard et ses chaussons, même dans la cuisine.
  This means In cold weather, she keeps her scarf and slippers on, even in the kitchen.

The original sentence is completely natural, though, especially if the idea is that she does not take them off.

Most naturally, it describes a general habit:

• When it’s cold, she keeps her scarf and slippers on even in the kitchen.

French present tense often works this way. Without extra context, a native speaker will usually understand this as something she tends to do whenever the weather is cold.

If you wanted to make it clearly about one specific moment, the context would usually make that clear.
