The relative being of the same person with the antecedent, the verb always agrees with it: as, “Thou who learnest Syntax.” “I who enlighten thy mind.”
The relative what (incorrectly pronounced) is sometimes used in a manner which is very exceptionable: as, “The gentleman wot keeps the wine-vaults.” “None but lovers can feel for them wot loves.” We mention this error once more, in order to insure its abandonment.
The objective case of the personal pronouns is by some, for want of better information, employed in the place of these and those: as, “Let them things alone.” “Now then, Jemes, make haste with them chops.” “Give them tables a wipe.” “Oh! Julier, turn them heyes away.” “What’s the use o’ mancipatin’ them niggers?” “Don’t you wish you was one of them lobsters?” “I think them shawls so pretty!” “Look at them sleeves.” The adverb there, is sometimes, with additional impropriety, joined to the pronoun them: as, “Look after them there sheep.”
The objective case of a pronoun in the first person is put after the interjections Oh! and Ah! as, “Oh! dear me,” &c. The second person, however, requires a nominative case: as, “Oh! you good-for-nothing man!” “Ah! thou gay Lothario!”
“Oh! you good-for-nothing man!”
RULE VI.
When there is no nominative case between the relative and the verb, the relative itself is the nominative to the verb: as, “The master who flogged us.” “The rods which were used.”
But when the nominative comes between the relative and the verb, the relative exchanges, as it were, the character of sire for that of son, and becomes the governed instead of the governor; depending for its case on some word in its own member of the sentence: as, “He who is now at the head of affairs, whom the Queen delighteth to honour, whose Pavilion (if the Court had been there) might have been at Brighton, and to whom is intrusted the helm of state—is a Lamb.”
