To answer your question:
Clove is a woman who identifies as non-binary.

As much as we'd all like it, she's not a femboy and neither does she have a little penis.

Justification:

• Her voice actor is also a woman who identifies as non-binary, thus her vocal chords clearly have XX chromosomes.
• If she has XX chromosomes in her vocal chords she also has XX chromosomes everywhere else.
• She has a feminine frame: lack of broad shoulders and developed cheek bones and calves, wide hips (especially visible upon ulting).
• Appealing to the collective subconscious, all of her fanarts depict her as a woman.
• Lastly, only women are capable of losing a pet rock.

This is all conclusive proof that Clove is indeed a woman.
