What does determining mean?
"Determining" is the present participle and gerund of the verb "determine," one of English's most versatile words for fixing or establishing something with certainty. In its most common sense, it means discovering or ascertaining a fact through investigation or calculation, as when researchers spend years determining the age of a fossil. It can also mean deciding or settling a matter authoritatively, as when a judge is responsible for determining guilt or innocence. Perhaps most distinctively, "determining" describes whatever controls or shapes an outcome: economists speak of interest rates as a determining force in housing markets, and biologists of genes as determining physical traits. When placed directly before a noun it works adjectivally — "the determining factor" is among its most frequent pairings — signalling the element that tips the scales. Formal and precise in tone, the word conveys rigor rather than guesswork, which makes it indispensable in scientific, legal, and analytical writing where certainty matters.
Present participle and gerund of "determine": to ascertain, establish, or decide something conclusively; or (of a factor) to control or fix an outcome.
"The committee is still determining the final budget for next year."
(Attributive use) Serving to decide or settle an outcome; decisive.
"Access to capital proved the determining advantage for the startup."
Almost always appears immediately before the noun it modifies, most commonly in "the determining factor."
When scientists say DNA is the 'determining' factor of your traits, they're using a word whose Latin root literally means 'to set boundaries' — your genes are drawing the limits.

Etymology of determining
The word traces back through Middle English and Old French "determiner" to the Latin "determinare," formed from "de-" (completely) plus "terminare" (to set bounds or limit), itself derived from "terminus," meaning boundary or limit. To determine originally meant to fix the exact limits or definition of something, and that sense of precision survives today. The same Latin root gives us cognates such as "terminate," "terminal," and "exterminate."
