Why does the word scissors have a silent c in it, and is it related to the word shears? Let’s find out.
Scissors [ˈsɪzəz / ˈsɪzɚz] are:
- A tool used for cutting thin material, consisting of two crossing blades attached at a pivot point in such a way that the blades slide across each other when the handles are closed. [other meanings are available]
It comes from Middle English sisours (scissors, shears, [candle] snuffer), from Old French cusoirs (a cutting tool), from Late Latin cīsōria, from cīsōrium (a cutting tool), from Latin -cīsus or caesus (cut, hewn, felled, stuck, beaten), from *caedō (to cut, hew, fell, strike, beat), from Proto-Italic *kaidō (to cut, hew, fell), from Proto-Indo-European *kh₂eyd- (to cut, hew) [source].
The c was added to scissors during the 16th century due to the influence of the Medieval Latin word scissor (tailor, carver) and the Latin word scindō (to cut, tear, read, separate), which both come from Proto-Indo-European *skeyd- (to divide, split) [source].
Words from the same PIE root include cement, to excise, incision, precise and chisel in English, qeth (to cut) in Albanian, césped (lawn, grass, turf) in Spanish, précis (specific, explicit, sharp) in French [source].
In Old English, the word for scissors or shears was sċēar [ʃæ͜ɑːr], which comes from Proto-West Germanic *skāri, from Proto-Germanic *skēriz (cutting, cuttable), from *skeraną (to shear), from Proto-Indo-European *(s)ker- (to cut off, sever, separate, divide) [source].
Words from the same roots include shear(s), shred, share, scourge, sharp, scrotum, cortex and carnage in English, scheren (to shear) in German, skörd (harvest) in Swedish, ysgar (separation, split, divorce) in Welsh, cena (dinner) in Italian and Spanish, and harr (to weed, prune) in Albanian [source].
So, scissors and shears are not related.
Another word with a silent / unnecessary c is schist [ʃɪst], which refers to any of a variety of coarse-grained crystalline metamorphic rocks with a foliated structure that allows easy division into slabs or slates.
It comes from French schiste [ʃist] (shale, schist), from Latin lapis schistos (“stone that is easy to split”), from Ancient Greek σχῐστός [skʰis.tós] (skhĭstós, cloven, divided, divisible), from σχῐ́ζω [skʰíz.dɔː] (skhĭ́zō, to split, cleave, divide), ultimately from Proto-Indo-European *skeyd- (to divide, split) [source].
Words from the same PIE root include schism (a split or separation within a group or organization, typically caused by discord) and schizophrenia in English, scindere (to split up, divide, cleave) in Italian, and scheef (crooked, weird) in Dutch [source].
