Inflexion
INFLEXION (from Lat. infleclere, to bend), the action of bending inwards, or turning towards oneself, or the condition of being bent or curved. In optics, the term " inflexion " was used by Newton for what is now known as " diffraction of light " (q.v.). For inflexion in geometry see CURVE. Inflexion when used of the voice, in speaking or singing, indicates a change in tone, pitch or expression. In grammar (q.v.) inflexion indicates the changes which a word undergoes to bring it into correct relations with the other words with which it is used. In English grammar nouns, pronouns,, adjectives (in their degrees of comparison), verbs and adverbs are inflected. Some grammarians, however, regard the inflexions of adverbs more as an actual change in word-formation.
