Russian Dolls / Hint

Insert a word in it's entirety into another word to form a new word. None of the letters are anagrammed. Each of the clues can be read as "Insert the first word into the second word to form the third word". All nested words are three letters.

Example: use a lathe > cattail = went back (REturnED)

-1. brace partner > a famous Roberts = a type of trainer
