tilde
tilde
UK[ˈtɪldə]US[ˈtɪldə]
n
A mark (~) placed over a letter, especially n in Spanish to indicate a palatal nasal sound (as in señor) or over a vowel in Portuguese to indicate nasalization.
Etymology
The word 'tilde' entered English in the 19th century, borrowed directly from Spanish. The Spanish term itself originates from the Latin word 'titulus', meaning 'superscription', 'title', or 'label'. This Latin root reflects the mark's original function as a diacritical notation placed above a letter. The journey from a Latin word for a heading or inscription to the specific name for a wavy diacritical mark illustrates the specialization of terminology in written language systems.
Analysis
The word is a simplex loanword from Spanish. It cannot be meaningfully segmented into productive morphemes in English.
