Others and different... Alien would be good too.
Phili (fili) is kiss in modern Greek; and
Phileo means 'love' -- as does 'agape'.
North American Greeks are not proficient in the modern or ancient Greek languages to make these 'assumptions' (corrections), as they only end up confusing people.
I suggest just sticking to the facts -- and if you don't know, you don't even need to actually open a book. Just Google it.
If you want to mark Greek word accents as in "ophthalmós", you should do so in every word, so anér, biblíon, theós, mikrós, gumnós etc.
The gymnos took a while. First associatio was gymnasium and I remember that originally didnt meant school, but a place where they did sports, (indeed naked, but took a while before that detail came up) so tried exercise, body, sports first, I was starting to think I was on the wrong path completely, but then thought, could it be naked...? And it was ! somehow I really dont feel that gymnos should be the word for naked. Just a completely ungrounded feeling, some words seem to work or fit for a definition even if you dont know the exact meaning ( ok if you dont get what I mean, the last few sentences will look like gibberish haha)
Ofthalmós is how the modern Greek is anglicized. The ancient is ophthalmos.
Pick Y or U for single upsilon and stick with it. It’s either gymnos/ichthys or gumnos/ichthus. The usual way to do it is with a Y, like in ichthyology.
Why are phileo and klepto the only verbs? Makes better sense to stick to noun (and adjective) forms: philia and kleptes. The roots are still recognizable.
You’ve got andros in the genitive (possessive) form just because it makes connecting with English derivatives easier. But would you put “man’s” on a similar English quiz? The form you want is aner. You could put andros in parentheses to help people out.
