The Etymology of Strait
Strait and straight were once the same word.βββββββββββββββββββββββββββββββββββββββββββββββββββββββββββββββ Both descend from Latin 'stringere,' meaning to draw tight or compress, which produced Old French 'estreit' and Middle English 'streit.' Until the 16th century, English writers used these spellings interchangeably for meanings ranging from 'narrow' to 'direct.' The split happened gradually: 'strait' kept the sense of tightness and narrowness, while 'straight' took on the geometric meaning of a direct line. The geographical use appeared early in the 14th century, when English sailors adopted the word for narrow sea passages they encountered during trade voyages. The figurative expression 'dire straits' preserves the older sense of being squeezed into a dangerous position. A straitjacket is named for its tightness rather than its shape.
