Synonym discussion

Sense: noun/5

All four words relate to something that must be fulfilled before something else can happen or be agreed. 'Condition' (noun/5) is the broadest of the group — it can refer to a rule in a contract, a prerequisite in daily life, or a clause in a formal agreement. 'Requirement' is stronger and less negotiable; if something is a requirement, it is mandatory and cannot be waived. 'Stipulation' is more formal and specific to legal or official contexts — it emphasises that a detail has been explicitly stated in writing. 'Term' usually appears in the fixed pair 'terms and conditions', where 'terms' cover the broader framework (price, duration, scope) and 'conditions' refer to the specific rules or limitations. For example, a rental agreement might state: 'One condition of the lease is no pets,' while the requirement of a first-month deposit is a different kind of obligation. Use 'requirement' when the focus is on necessity, and 'condition' when the focus is on a rule that must be met.

Etymology

LatinOld FrenchEnglish

The word 'condition' comes from the Latin word 'condicio', meaning 'an agreement' or 'a situation'. It entered English through Old French 'condiciun' in the 14th century. The original meaning was 'a stipulation or term in an agreement,' which later broadened to include 'the state or situation something is in.' The verb senses developed around the 16th century, first meaning 'to make an agreement' and later evolving into 'to train or influence' in the 19th century through psychological terminology.
