Slightly

Slightly is an adverb used to express a small amount, degree, or extent. It commonly modifies adjectives, other adverbs, or verbs, signaling that something is not wholly but only to a small degree.

In sentence position, slightly usually appears directly before the word it modifies, as in slightly warmer weather or adjust slightly. It can also follow the verb in constructions like The soup is slightly spicy. When used with comparatives, it can appear before phrases such as slightly more or slightly less. The word tends to soften statements or indicate a minor, rather than decisive, difference, making it suitable for careful or cautious wording.

Usage notes and nuance: Slightly implies a measurable but modest change or quality. It is less forceful than words like somewhat or moderately, and more precise than slang terms. In formal writing, slightly is preferred when a small degree needs to be conveyed without making a strong claim. In casual speech, alternatives such as a little or a bit may be common, though slightly remains widely understood and acceptable in many registers.

Etymology and related terms: Slightly derives from the adjective slight, which historically carried senses of small, minor, or trifling. Related words include somewhat, somewhat, a little, and to a lesser degree. Antonyms emphasizing larger degrees include greatly, substantially, and markedly.
