nonbinary means someone who identifies outside of the gender binary. the gender binary consists of man & woman. any identity out of the binary is nonbinary. transgender describes someone who doesnt identify with the gender they were assigned at birth, so if someone was assigned male at birth but identifies as female, they r a trans binary person. and if someone assigned female at birth identifies as genderfluid, they r a trans nonbinary person. however some nonbinary people dont like to use the word trans for themselves so yea
