Which one should you use?

To express the English sense of 'definitely' (meaning 'certainly' or 'without a doubt'), use certainement or assurément instead of définitivement.

English speakers often use définitivement to mean 'definitely' (certainly), but in French it primarily means 'permanently' or 'for good'.

In very informal French, the word grave is used as a slang version of 'definitely'. While it usually means 'serious', it acts as an intensifier to agree with a statement.
To say 'definitely' in a casual way, French speakers often use carrément, which literally means 'squarely'. It suggests that something is completely or totally true.
In Quebec, the influence of English has led many speakers to use définitivement to mean 'certainly'. However, this usage is often viewed as an error or a 'calque' by speakers in France.
