4) The Suppositional mood expresses analytically a problematic action, not contradicting reality. The realization of the action may depend on certain circumstances. E.g. Should you meet him, tell him to come
Suppositional mood specializes in the expression of hypothetical actions. The comparison of such sentences as
"If he turns up tell him to -wait for me" and
"Should he turn up tell him to wait for me“
shows that both the verbal forms present the action as hypothetical but differ in the degree of certainty which is higher in the case of Present Indefinite Indicative
