What it does: modifiers set the dial between certainty and doubt. Intensifiers (utterly, perfectly) turn the claim up; limiters (almost, barely, still, no longer, half-) turn it down or set a timer on it. A strategic limiter can carry an entire plot in one syllable, and a placed adjective can editorialize with a raised eyebrow (her careful brother).

The deed was signed. The house was almost hers, the almost being her brother’s name still on the lien.
The grammar of ownership is complete — subject, verb, possessive. The modifiers quietly un-complete it: almost removes the arrival, still sets a clock running on it. Two small words, the whole inheritance dispute.
Claim it whena limiter changes the standing of a fact — ownership, success, memory, forgiveness — not when an adjective merely names a quality.
Lock it in withthe modifier–noun pair quoted together: almost hers, not almost. The pair is the evidence; the lone adverb is decoration.
Don’t confusemodifiers with grammatical mood — indicative, imperative, subjunctive are verb forms (“If the house were hers” is subjunctive, not a modifier), and strings of adjectives usually signal diction or pacing work instead.
