adverb

tellement

so · so many

Cela sert à dire qu’il y a une grande quantité ou un haut degré de quelque chose.

The word "tellement" in French means "so" or "really," and it is used to emphasize the degree or extent of something. It is often employed to accentuate a statement, indicating a strong level of feeling or intensity.

For example:

"Il fait tellement chaud." (It's so hot.)
"J’aime tellement ce livre!" (I really love this book!)

Synonyms and differences:

Ainsi: Typically translates to "thus" or "so" in a more formal context; it does not usually specify emotional intensity or emphasis.
Si: Used in a way that might translate to "so" for expressions of emphasis but is often followed by an adjective directly, like "si beau" (so beautiful). It's also used in conditional sentences but doesn't capture the broader emphasis of "tellement."
Tant: This word means "so much" or "so many" and conveys a similar emphasis, but it's often used in contexts dealing with quantity or extent rather than emotional intensity.

In summary, "tellement" is used to convey a high degree of an emotion or trait in everyday language, while synonyms may emphasize different aspects of comparison or quantity.
