La sécheresse abîme le feuillage.

Sécheresse means drought or dryness, depending on context. In this sentence, it means drought.

It is feminine because that is simply the grammatical gender of the noun in French: la sécheresse.
Like most French nouns, its gender has to be learned with the word.

It is related to the adjective sec / sèche, meaning dry.

Here, abîme is the verb abîmer, and it means damages, harms, spoils, or wears down.

So:

• La sécheresse abîme... = Drought damages...

Be careful: un abîme also exists as a noun meaning an abyss, but that is a different word. In your sentence, abîme is definitely the verb.

Because abîme is the conjugated form of the verb, while abîmer is the infinitive.

The subject is la sécheresse, which is third person singular, so the verb becomes:

• abîmer = to damage
• la sécheresse abîme = drought damages

This is just like:

• to damage → damages
• abîmer → abîme

French often uses definite articles where English might use no article or a more general expression.

So French says:

• La sécheresse abîme le feuillage.

Literally, that looks like:

• The drought damages the foliage.

But in natural English, this may simply mean:

• Drought damages foliage.

French often uses le / la / les to talk about things in a general sense:

• Le chocolat est bon. = Chocolate is good.
• La musique me calme. = Music calms me.

So the articles here are normal and do not necessarily mean one specific drought or one specific set of leaves.

Feuillage means foliage, leaf cover, or all the leaves of a plant or tree considered together.

So:

• les feuilles = the individual leaves
• le feuillage = the foliage as a whole

French uses feuillage when talking about the leafy mass or the plant’s leaf growth in a more general or collective way. That makes it a very natural word in a sentence about weather or plant damage.

Because feuillage is a collective noun. It refers to foliage as one whole mass, not to separate leaves one by one.

That is similar to English foliage, which is also usually singular:

• The foliage is damaged.

So le feuillage is singular even though it refers to many leaves.

A simple pronunciation guide is:

lah say-sheh-RESS ah-BEEM luh fuh-YAHZH

A few notes:

• sécheresse: the ch sounds like sh
• abîme: the î does not change pronunciation much in modern French; it sounds like ee
• feuillage: the ill here sounds like y, so feuillage is roughly fuh-yahzh

A more IPA-like version is:

[la se.ʃə.ʁɛs a.bim lə fœ.jaʒ]

The accents help with spelling and sometimes pronunciation or word history.

• sécheresse has é, which clearly gives an ay-like sound
• abîme has î, a circumflex

In modern French, the circumflex in abîme usually does not strongly change pronunciation. It is mostly part of the standard spelling and sometimes reflects older historical forms.

So yes, you should write the accents correctly, even if they do not always make a big difference in speech.

It can often mean drought in general, especially as a general statement or fact.

French commonly uses the definite article for general truths:

• La sécheresse abîme le feuillage. = Drought damages foliage.

Depending on context, it could also refer to a specific drought, but without more context, many learners should understand it as a general statement.

Yes. Some common alternatives are:

• endommage = damages
• dessèche = dries out
• détruit = destroys
• affecte = affects
• fragilise = weakens

For example:

• La sécheresse endommage le feuillage.
• La sécheresse dessèche le feuillage.

But abîme is a good everyday verb because it gives the idea of causing harm or deterioration without necessarily meaning total destruction.

No. The word order is very standard French:

• La sécheresse = subject
• abîme = verb
• le feuillage = direct object

So it follows the basic pattern:

Subject + Verb + Object

Just like in English:

Drought damages foliage.

It sounds natural and correct. It is slightly more descriptive or informational than very casual conversation, mostly because of the noun feuillage, which is a bit more specific than everyday words like les feuilles.

So it would fit well in:

• weather reports
• gardening
• environmental discussion
• school textbooks
• articles about nature

It is not strange or overly formal; it is just a fairly neat, standard sentence.
