Examples

Morphology

sex-linked = sex + link (transparent) = sex + link + ed

Meaning is directly derived from 'sex' + 'linked' (i.e., linked to sex/chromosomes); the compound is straightforward for learners who know the parts.

Etymology

Sex-linked comes from two parts: sex meaning 'male or female' and link meaning 'connected'. It refers to traits that are 'connected' to a sex chromosome, often the X chromosome, so they can appear differently in males and females.
