an adjective is a word that modifies a noun or pronoun in order to describe, clarify, or give a specific meaning to the other word. In the case of 'inevitable', it would be used to describe a noun or situation that cannot be avoided, avoided, or prevented.
'inevitable' is an absolute adjective; that is, it does not need to be modified by an adverb to account for degree (e.g. 'mostly, somewhat'). It can be used to describe a future event or situation that is certain to happen, along with its associated consequences.
1. The current trajectory of our planet’s climate suggests that certain environmental disasters are inevitable.
2. The effects of their ongoing financial mismanagement ultimately led to an inevitable bankruptcy.
3. Both parents knew it was inevitable that their child would grow up too soon.
It is important to note that 'inevitable' is often used to describe something that is unpleasant or negative. Therefore, it is important to be aware of cultural context when using this word so as not to cause any negative connotations. Additionally, it tends to suggest a sense of finality, so using more neutral language may be better in cases where one is unsure of the implications of the situation.
