What does deciding mean?
'Deciding' is the present participle of the verb 'decide', which traces back to the Latin 'decidere', meaning literally 'to cut off' — a fitting image for an act that eliminates every option except one. In everyday use, it describes the ongoing process of weighing choices and reaching a judgment: deciding what to eat, where to live, whom to trust. The word also works as an adjective in well-established phrases such as 'the deciding factor', 'the deciding vote', and 'the deciding moment', where it marks whatever element finally settles an outcome. This adjectival sense carries a tone of consequence and finality, often appearing in journalism, sport, and law to identify the turning point of an event. Related forms include 'decision', 'decidedly', and the adjective 'decisive', which is generally preferred when describing a settled outcome directly. Whether describing deliberation in progress or the element that tips the scales, 'deciding' captures the pivotal act of choosing.
Making a choice or reaching a conclusion after consideration; forming a judgment about something.

Etymology of deciding
'Deciding' derives from the Latin 'decidere', formed from 'de-' (off) plus 'caedere' (to cut), so the original sense was 'to cut off' other possibilities. The word passed into English via Old French 'decider' in the late Middle Ages, with its modern sense of resolving a question established by the sixteenth century. It shares its root with 'decision', 'decisive', and 'concise' (from the same Latin verb 'caedere'), making 'cutting away alternatives' a common thread across this word family.
