Sense: adjective/2

'Unconditional' is the most common and natural choice for describing something given without requirements — 'unconditional love', 'unconditional surrender'. 'Absolute' emphasises total completeness rather than the absence of terms: 'absolute power', 'absolute certainty'. 'Unrestricted' focuses on freedom from rules or limits: 'unrestricted access', 'unrestricted movement'. 'Unlimited' suggests no upper bound: 'unlimited time', 'unlimited resources'. While 'unconditioned' overlaps with these, it is far less frequent and feels more technical or legal. Use 'unconditional' instead in almost all everyday situations — for example, 'She gave her unconditional support' sounds natural, while 'She gave her unconditioned support' sounds stilted.

Etymology

LatinFrenchEnglish

Formed in English by adding the prefix 'un-' (meaning 'not') to 'conditioned', which comes from the Latin word 'condicio' meaning 'agreement, terms, or arrangement'. The general sense of 'not subject to conditions' appeared in the mid-1600s. The specific psychological meaning — describing a natural, unlearned reflex or response — emerged in the early 1900s through the work of physiologist Ivan Pavlov on classical conditioning.
