Morphology

arachnoid = arachnid (transparent) = arachno + oid

Formed from the spider-related combining form 'arachno-' plus '-oid', so the meaning 'spider-like' is directly inferable.

Etymology

Arachnoid comes from the Greek arachne 'spider' and the ending -oid 'like', so it literally means 'spider-like' or 'web-like' and is used for things that look like spiders or their webs.
