Following the lead of George Scheetz in compiling lists of words with a common ending, I have chosen words ending in -IFER, the majority of which derive from the suffix meaning 'to bear' or 'to carry'. Numbers of words ending in -IFERA and -IFEROUS have no sanctioned curtailments to -IFER, even though such words would be logical derivations. Except as noted, all words are in the Merriam-Webster unabridged dictionary.
