'gland-related' originates from the word 'gland,' which comes from the Latin word 'glandula,' meaning 'acorn' or 'gland.' The suffix '-related' is used to indicate association or connection.

'gland' changed from the Latin word 'glandula' and eventually became the modern English word 'gland.'

Initially, 'gland' referred to a small, rounded mass, similar to an acorn, but over time it evolved to refer to a specialized organ in the body that secretes substances.
