What does complying mean?
Complying is the present participle and gerund form of the verb comply, meaning to act in accordance with rules, laws, orders, standards, or requests. To be complying with something is to behave as that rule or authority demands rather than ignoring or resisting it. The word is common in legal, business, and regulatory contexts: companies complying with safety codes, citizens complying with tax laws, or products complying with technical specifications. It almost always takes the preposition 'with' to introduce whatever is being followed. The tone is neutral to formal, carrying connotations of obedience, cooperation, and legitimacy rather than enthusiasm — one can comply grudgingly as easily as willingly. Related forms include compliance (the noun for the state of conforming) and compliant (the adjective). Etymologically, comply derives through Spanish cumplir from Latin complere, meaning 'to fill up' or 'to complete,' so complying literally suggests completing or fulfilling what is asked.

Complying traces back to the Italian 'compiere', meaning to complete or fulfill — so when you comply with a rule, you're literally 'completing' what it asks of you.

Etymology of complying
Complying comes from the verb comply, which entered English in the early 17th century via Spanish cumplir, ultimately deriving from Latin complere, meaning 'to fill up' or 'to complete.' The same Latin root gives English words such as complete, complement, and implement. In its original sense, comply could mean simply to fulfil or carry out an action, but over time it narrowed toward the modern sense of yielding to rules or the wishes of others, now expressed chiefly in the phrase 'comply with.'

How complying is actually used
Register is neutral to formal; complying appears most often in legal, regulatory, business, and bureaucratic contexts. It typically requires a following phrase introduced by 'with' ('complying with the rules'), which is grammatically obligatory. As a gerund it can serve as a noun-like subject or object ('complying was not optional').
