Conditional

Question

Should anyone object, they must be told to put their complaint in writing.What type of conditional is this sentence? number 1?

Fivejedjon · Accepted Answer

They are predictive conditionals, referring to fuutre time, They therefore perform the same function as the traditional first conditional:

When speakers present an action or state in predictive conditional terms, they are stating that the future [non-]occurrence or [non-]existence of an action or state is a consequence of some really possible prior action or state:

24 If it’s fine tomorrow, we will have a barbecue.
25. If Mary phones, let’s invite her to dinner.
26. If you’re getting bored, why don’t you do something else?
27. We’re going to take strike action if they won’t give us a rise.
28. If you will come with me, I’ll take you to the meeting.
29. If the offer has arrived by the end of the week, we’ll accept.
30. If I’m not in the office tomorrow, I’ll have caught the bug that’s going around.
31. I may resign if David gives Celia the job,
32. If Romana arrives tomorrow, I take her to see the new play.
33. If Romana arrives tomorrow, she will have completed the job.
34. George will be here soon, if he managed to catch the train.

Of these seven examples, only #24 fits into the traditional view of First Conditionals:

FIRST CONDITONAL

IF + Present Simple, WILL +Infinitive [Future]

future realpossibility

If you do not pass the test, you will fail the course.

However, #25 to #34, along with many other possible combinations of tenses and modals, are naturally occurring predictive conditionals. The only ‘rule’ about tenses is the logical one that if we are talking about a real possibility, then we cannot use a form of the verb to distance in reality. There is no restriction on forms which show how speaker views the situation. The speaker views the main-clause, for example, ascertain (#24), a suggestion (#25), an action for which there is present evidence (#27) , etc. The antecedent action or state is viewed as future (#24, #25, and #27-#33), present (#26) and past (#34). In #28, the antecedent state is a present or future willingness.

The use of the present tense in the main clause of #32 removes all suggestion of ideas such as volition, present evidence or possibility. The future taking of Romana to see the new play is presented as a simple fact, dependent only on her future arrival. In #33, the consequence of the possible antecedent is not the prior actual completion, but the certainty of the prior completion. This becomes clear if we paraphrase the utterance:

33a. If Romana arrives tomorrow, the reason will be... (that she completed the job before her arrival)

In #27, the use of [the negative form of] will implies that the speaker considers their present or future refusal [this will be made clear from context] as an annoying orwilful characteristic.

In #28, will implies a willingness on the part of the person addressed to comply with the speaker’s request.

As we have just seen, we can use will with certain meanings in the IF-Clause. However, it would be illogical to use will with the meaning of certainty [or indeedmay with the meaning of possibility] in a clause in which IF itself impliespossibility/uncertainty. This is why we do not produce such utterances as:

35 *If it will rain tomorrow, we will stay at home.

and why #36, below, can normally indicate only willingness on Wendy’s part, not certainty:

36. If Wendy will write the report, I won’t have to ask Jim.

As with Factual conditionals, the possible range of tense- and modal-use in Predictive Conditionals is helpful rather than confusing for learners. Provided you understand how the tenses are used, you can say what you wish to say; you are not constrained by arbitrary rules about ‘sequence of tenses’. The only ‘rule’ is moderately self-evident: when we speak about possible future situations, we can use a verb form to distance in directness, as in: if you’d take a seat over there, I’ll tell Mr Morrison you’re here, but not one to distance in reality or time.

SHOULD

Should can be used in the IF-clause, with a meaning similar to ‘happen to/chance to’suggestingthat the speaker sees the possibility as real, but more remote than with an unmarked [present] tense:

37. If you should run into Paul, give him my regards.

This is one of the few anomalies in the system. Should is the form of the modal shall that is distanced in reality or likelihood. Such distancing forms of the other modals are, logically enough, not used in a Predictive Conditional sentence implying a real possibility.

Do you mean that my original is the same as:

If I should see him, I'll invite him. (less probable)

Fivejedjon · Answer

Your original was : Should anyone object, they must be told to put their complaint in writing/ Thos is roughly equivalent in meaning to:

If anyone should object, they must be told to put their complaint in writing.
If anyone objects, they must be told to put their complaint in writing.

I've heard that this usage of should suggests that something is unlikely, or not particularly probable. Do you agree with that?

Fivejedjon · Answer

Yes. I have already said: Should can be used in the IF-clause, with a meaning similar to ‘happen to/chance to’suggesting that the speaker sees the possibility as real, but more remote than with an unmarked [present] tense:
