Thief is a common class noun; the connection shows a male is meant, therefore masculine gender; singular number; object of the verb takes, hence objective case.
Throat is neuter, of the same class and number as the word neckcloth; it is the object of the preposition by, hence it is objective case.
NOTE.—The preposition sometimes takes the possessive case (see Sec. 68).
Morning is like throat and neckcloth as to class, gender, and number; as to case, it expresses time, has no governing word, but is the adverbial objective.
