Ivyle is a gender similar to or related to male, but for those who are disconnected from maleness or masculinity, like their maleness or masculinity is off or atypical or different in some way from typical men. This is not being partially a man, but being 100% a separate, man-like gender. This gender may be masculine-aligned and/or male-aligned, but it doesn't have to be either.
The ivyle equivalent of "man" is ivyn, "masculine" is "ivyline", and "boy" is "ivy".
The feminine/female equivalent is lilyale.
