|Towards more picturesque speech™
An old favourite, applicability started out life as a verb (“apply”), became a noun (“application”), became an adjective (“applicable”, shape-shifted then into a new verb — albeit a passive one — (“to be applicable”), and eventually settled on a life of tiresome nounitude in its adult form as “applicability”.
But at what cost to the reader? Without thinking on it, choose your favourite:
This clause applies.
This clause is applicable.
Also a more pernickety but equally redundant way of saying “relevant”: “The users shall comply with all applicable contractual provisions” — seeming to suggest that users might be compelled otherwise to comply with provisions that didn’t apply.
That’s not how a contract works, peeps.
