Long thin pieces of thread, hair, or rope twisted together; or stretches of beach; or becomes left helpless.
Old English 'strond' or 'strand' meaning shore or beach (Scandinavian origin). The 'thread' meaning came later. The verb 'strand' (to leave stranded) derived from ship terminology.
A ship running aground was 'stranded on the strand' (beach)—so the word for 'being stuck helpless' literally came from beach vocabulary, which is why we call deserted sailors 'stranded.'
