Surface Forms

trichiasis singular
trichiases plural

Morphology

trichiasis = hair (opaque) = trich + iasis

Formed from medical combining elements 'trich-' (hair) + '-iasis' (disease) which are specialized combining forms not recognizable to average learners, so the connection to 'hair' is not obvious from form.

Etymology

Trichiasis comes from Greek parts trich- meaning 'hair' and -iasis meaning 'condition' or 'disease'. So it literally means a 'hair condition', which fits because trichiasis is when eyelashes grow inward and irritate the eye.
