Paronymy is the relationship between a pair of words or phrases which are similar or partially identical in spelling, pronunciation and/or meaning. [1] In the discussion of semantic analysis, the term paronym can also be used in a narrower sense to refer to words that are derived from the same root, i.e. cognate words. [2] [3]
An object that is not chiral is said to be achiral. A chiral object and its mirror image are said to be enantiomorphs. The word chirality is derived from the Greek χείρ (cheir), the hand, the most familiar chiral object; the word enantiomorph stems from the Greek ἐναντίος (enantios) 'opposite' + μορφή (morphe) 'form'.
Not to be confused with helicity, which is the projection of the spin along the linear momentum of a subatomic particle, chirality is an intrinsic quantum mechanical property, like spin. Although both chirality and helicity can have left-handed or right-handed properties, only in the massless case are they identical. [ 5 ]
The triple bar character in Unicode is code point U+2261 ≡ IDENTICAL TO (≡, ≡). [1] The closely related code point U+2262 ≢ NOT IDENTICAL TO (≢, ≢) is the same symbol with a slash through it, indicating the negation of its mathematical meaning.

A thesaurus or synonym dictionary lists similar or related words; these are often, but not always, synonyms. [15] The word poecilonym is a rare synonym of the word synonym. It is not entered in most major dictionaries and is a curiosity or piece of trivia for being an autological word because of its meta quality as a synonym of synonym.
However, Stephen Palmquist holds that "noumenon" and "thing-in-itself" are only loosely synonymous, inasmuch as they represent the same concept viewed from two different perspectives, [17] [18] and other scholars also argue that they are not identical. [19] Schopenhauer criticised Kant for changing the meaning of "noumenon".
Due to their similar yet non-identical pronunciation in American English, ladder and latter do not qualify as homophones, but rather synophones [10] or homoiophones. [11] [12] Heteronyms (literally "different name") are the subset of homographs (words that share the same spelling) that have different pronunciations (and meanings).
