The English modal verbs are a subset of the English auxiliary verbs used mostly to express modality (properties such as possibility, obligation, etc.). They can be distinguished from other verbs by their defectiveness (they do not have participle or infinitive forms) and by their neutralization (that they do not take the ending -(e)s in the third-person singular).
The principal English modal verbs are can, could, may, might, shall, should, will, would, and must. Certain other verbs are sometimes, but not always, classed as modals; these include ought, had better, and (in certain uses) dare and need. Verbs which share only some of the characteristics of the principal modals are sometimes called "quasi-modals", "semi-modals", or "pseudo-modals".

    Let’s talk taps-ceramic vs rubber washer.

    Some years ago you could fit a pair of taps with the understanding that when they eventually began to leak, you could simply replace the rubber washer. Don’t get me wrong. I’m all for embracing new technology, but have you ever tried to match up (find) a replacement ceramic insert for the...
