    Usage notes

    * Should'' has, as its most common meaning in modern English, the sense ''ought'' as in ''I should go, but I don't see how I can''. However, the older sense as the subjunctive of the future indicative auxiliary, ''shall'', is often used with ''I'' or ''we'' to indicate a more polite form than ''would'': ''I should like to go, but I can't''. In much speech and writing, ''should'' has been replaced by ''would'' In contexts of this kind, but it remains in conditional subjunctives: ''should'' (never ''would'') ''I go, I should wear my new dress . * (obligation) Contrast with stronger auxiliary verb (must), which indicates that the subject is required to execute the predicate. * (likely) Contrast with stronger auxiliary verb (must), which indicates that the subject certainly will execute the predicate. * See the usage notes at (shall).
