unequivocal
"Unequivocal" is a powerful adjective with essentially one strong, clear meaning — which is quite fitting, given what the word actually means! It's used when something is so clear and certain that there is absolutely no room for doubt or misunderstanding.
When something is unequivocal, it leaves zero doubt. There is only one possible way to understand it — no confusion, no 'maybe', no 'it depends'. Think of it as the opposite of being vague or wishy-washy. If someone gives you an unequivocal answer, you know exactly where they stand.

You can also use 'unequivocal' to describe support, praise, or belief that is total and without any reservation. If someone is an unequivocal supporter of something, they back it 100% — no hesitation, no 'but...'.
