Wrong: 'what (that which)' defines, the 'and which' clauses do not.
(ii) Latent coordination, between relative clause and equivalent, is seldom correct when the relative clause is non-defining; for the equivalent, with few and undesirable exceptions, is always a defining adjective or phrase, and can be coordinate only with a defining clause. The equivalent must of course be a true one; capable, that is, of being converted into a relative clause without altering the effect of the sentence. Neglect of this restriction often results in false coordination, especially in one particular type of sentence. Suppose that a historian, after describing some national calamity, proceeds: 'In these distressing circumstances...' Here we might seem to have two possible equivalents, 'these' and 'distressing'. First let us expand 'these' into a relative clause: 'In the distressing circumstances that I have described'. This, in the context, is a fair equivalent, and as often as not would actually appear instead of 'these'. But next expand 'distressing': 'In these circumstances, which were distressing', a non-defining clause. To this expansion no writer would consent; it defeats the object for which 'distressing' was placed before the antecedent. That object was to record his own sensibility without disparaging the reader's by telling him in so many words (as our relative clause does) that the circumstances were distressing; and it is secured by treating 'distressing' not as a separate predication but as an inseparable part of the antecedent. 'Distressing', it will be observed, cannot give us a defining clause; it is obviously meant to be co-extensive with 'these'; we are not to select from 'these' circumstances those only that are 'distressing'. Moreover, as 'these', although capable of appearing as a relative clause, can scarcely require another relative clause to complete the limitation of the antecedent, it follows that in sentences of this form coordination will generally be wrong. We have examples in the
