Forms

phénoménal (feminine phénoménale, masculine plural phénoménaux, feminine plural phénoménales)[1]

Etymology

It is formed from French phénomène + -al.[2][1][3][4] Phénomène is from Ancient Greek φαινόμενα (phainómena, “celestial phenomena, things that appear”), from φαίνω (phaínō, “to show, appear”).[4]

Earliest recorded meaning

It is first recorded in 1803 in Boiste's dictionary, with a reference to Kant, meaning “belonging to or relating to phenomena”.[2][5][6]

Semantic evolution

The adjective began as a term of philosophy: Kant's distinction between the phenomenal and the noumenal world gave it its first sense, “of the nature of a phenomenon, of the fact perceived by the senses”.[2][5][7] Bloch and Wartburg note that its meaning then developed in parallel with that of phénomène, which had come to mean anything surprising.[4] The Académie's supplement of 1827 records the everyday sense “extraordinary, prodigious”, said of the effect of something marvellous.[2][5]

Littré still marked the word as a neologism and called the sense “surprising” familiar and jocular.[8] The GLLF dates its use of a remarkable person to the early 20th century.[6] The adjective gave the philosophical terms phénoménalisme (1823) and phénoménalité (1833), and the adverb phénoménalement (1823).[5]
