The word elytra refers to
one of the anterior wings in beetles and some other insects that serve to protect the posterior pair of functional wings
The pronunciation given by Merriam-Webster is \ˈe-lə-trə\, which translates to /ˈɛlətrə/ in IPA.
Other somewhat reliable sources also say one of /ˈɛlɪtrə/, /ˈɛlətrə/, and /ˈɛlaɪtrə/:
(In fact, many dictionaries don't list this word at all.)
However, it seems that the pronunciation /ˈɛlɪtrə/ or /ˈɛlaɪtrə/ does not reflect actual pronunciation. Almost every time a YouTuber read this word, I hear either
/ɪˈlaɪtrə/ (or /əˈlaɪtrə/); or
/ɪˈliːtrə/ (or /əˈliːtrə/).
In the recent YouTube video Minecraft, But We Can't Stop Flying... (no spam intended), for instance, YouTubers GeorgeNotFound (British; 0:11) and Dream (American; 2:35) both pronounced the word as /ɪˈlaɪtrə/ (or /əˈlaɪtrə/). In another Minecraft video, YouTuber Grian (British; 0:27) read /ɪˈliːtrə/ (or /əˈliːtrə/). So far, the former seems to be the more prevalent pronunciation among speakers with both British and American accents, but the fact that the common pronunciation contradicts the pronunciation listed in dictionaries and other sources surprises me.
