Should
SHOULD.
shood. The preterit of shall, but now used as an auxiliary verb, either in the past time or conditional present. 'He should have paid the debt at the time the note became due.' Should here denotes past time. 'I should ride to town this day if the weather would permit.' Here should expresses present or future time conditionally. In the second and third persons, it denotes obligation or duty, as in the first example above. 1. I should go. When should in this person is uttered without emphasis, it declares simply that an event would take place, on some condition or under circumstances.
But when expressed with emphasis, should in this person denotes obligation, duty or determination.
2. Thou shouldst go.
