Semifinally
"Semifinally" in a Sentence (2 examples)
Semifinally, when a pronoun is involved, the possessive case is invariable: “Dick is a friend of hers,” not “Dick is a friend of her.” Finally, despite the not infrequent questions that are raised, the double genitive is of long standing, idiomatic, useful and here to stay.
So he was finally, not semifinally but finally-finally, finished with alma mater?
