The SM. (also the Conditional M)
Probably the only thing linguists are unanimous about with the SM is that it represents an action as a non-fact, as something imaginary, desirable, problematic, contrary to reality. In all other respects opinions differ.
In modern E the SM has synthetic and analytical forms.
Synthetic(or simple forms)- are those the formal elements of which are to be found within 1 word from which they are inseparable. These are the present and the past Ind. Affirmative (sing, sings, sang); the non-perfect common aspect forms of the inf, partic.I, the gerund, part. II (sing, singing, sung); the IMP.M (sing!)
Analytical (or compound form) consists of at least 2 verbal elements- an auxiliary V and a notional V. the latter is presented be partic.I, II, or the infin. An auxiliary V is devoid of its lexical Mg, its role is purely structural. It may be finite or non-finite, thus showing whether the whole V form is finite or non-finite as in:
Means of expressing unreality:
Unreal actions are expressed by:
plain stem of the V for all persons (I insist that he be present)
were for all persons ( I wish I were 10 years younger)
the form of the Past Indef. (He looked as if he knew about it)
the form of the Past Perfect (He looked as if he had seen a ghost)
should for the 1st person Sing or Pl or would (for the other persons)+inf. (If I had a garden I should grow tulips there)
should \would +Perf. Inf (If it hadn’t rain I should have gone for a walk)
should( for all persons)+inf. (I insist that he should do it)
would (for all per.) +inf (I wish he wouldn`t interrupt me)
may\ might +inf. (I told u that so that you might write to ur parents)
can\ could +inf. (I told u that so that u could…)
were to (for all persons)+ inf. (If he were to discover the truth he would never speak to me)
An unreal action can be represented by these means as hypothetical (the realization is doubtful: (He insisted that the plan be discussed) and contradicting reality (the action can’t be realized) (I wish I can see the parade)
Other means: modal Vs (He must have gone)
Modal Ws (probably, perhaps)
