tilden.

/ˈtɪldeɪ/

Etymology: < Spanish tilde, a popular metathetic form of the type *tidlo for tit(u)lo , < Latin titulus title n. Diez cites as a parallel instance cabildo, Latin capitulum.

a. The diacritic mark ˜ placed in Spanish above the letter n to indicate the mouillé or palatalized sound /ɲ/, as in señor /sɛɲor/. Also, the mark placed in Portuguese above the letters a and o to indicate nasalization. Used similarly in systems of phonetic transcription. Originally the mouillé sound was written nn, as in the parallel ll; the tilde is an abbreviated form of the second n.
