Hold person specifies that it can only target humanoids:
Choose a humanoid that you can see within range[…]
The Minotaur creature stat block from the Monster Manual lists them as monstrosities, not humanoids, however nothing is mentioned of that in the racial stat block in Guildmasters’ Guide to Ravnica or Mythic Odyssey of Theros. Can a PC Minotaur still be targeted by the Hold Person spell, or other spells that specifically target Humanoids?
The only similar things I could find are the racial stat blocks for satyrs and centaurs, which have the change of being the fey creature type, rather than humanoid:
Fey. Your creature type is fey, rather than humanoid.
Does this imply all other player races are humanoid?
