Composition and lyrics
"Mother Tongue" has been described as a pop rock, dance-pop, and pop metal song. According to Jordan Fish, "Mother Tongue" is the spiritual successor of "Drown". The track is a love song dedicated to Oliver Sykes' wife, Alissa Salls. Fish said of the song: ""Vocal-wise it's quite a big song. There's a little bit of Portuguese in there, which is quite unusual. It's kind of a big, anthemic song. It's probably as close as we get to something like "Drown" on this album. It's a love song, so it's an emotional one.""
