Etymology
The word "invariably" is built upon the Latin verb variare, meaning "to change," which itself derives from varius (varied, diverse). The negative prefix in- is attached to form the concept of "not changing." This passed into English as the adjective "invariable." The adverbial suffix -ably was then appended, following the pattern of adjectives ending in -able, to create the adverb meaning "in an unchangeable manner." Thus, the literal sense of "in a manner not able to be changed" evolved into the modern abstract meaning of "always" or "without exception," describing a constant, predictable state or action.
Analysis
Structure: in (not) + vari (change) + ably (adverb suffix)
- in: Latin origin, a prefix meaning "not".
- vari: Latin origin, from the root of variare (to change, to vary), meaning "change".
- ably: English suffix, from Latin -abilis (able to be), forming adverbs meaning "in a manner that can be".
