Grammar concerns the forms of words and their dependent relations in the sentence. To illustrate this: It is “bad grammar,” ludicrously, monstrously bad grammar, to say in Latin, _Nos habeo bonus mater_, and yet these Latin words, literally and simply translated in their order, mean, We have a good mother, which in English is perfectly “good grammar.” In the Latin (to call it Latin) every word is wrong; in English every word is right. The reason of this is that in Latin words change their forms according to their relations, not according to their essential meaning. _Habeo_ means have; but it can not be used to express a plural having; that requires for _we_ (_nos_) the form _habemus_. _Bonus_ means good; but it can not be used to express the goodness of a feminine object, for which the form _bona_ is required. Yet further: Even _bona_ can not be used to qualify a noun which is the object of a verb, or, as we say, in the objective (or accusative) case, for which the form _bonam_ is required. _Mater_ means mother, but as the object of the verb _have_, _mater_ must change its form to _matrem_. By these required changes of form the Latin sentence becomes, _Nos habemus bonam matrem_, which is “good grammar,” although poor Latin, but which, after all the changes, means simply, We have a good mother; nothing more nor less. Yet further: The sentence, as written above, although grammatical, is poor Latin because it is at variance with the habit, or as it is sometimes called the spirit, or even the genius, of the Latin language. In Latin the word _habemus_ (although like _habeo_ it means simply, have) is so positively and distinctively limited in use to the first person plural that the pronoun _nos_—we—is quite superfluous, and is never used unless with an emphatic purpose; _habemus_, without the _nos_, means, we have. Moreover it was the Latin habit of speech to place the object generally before the verb; and good Latin for, We have a good mother would be, _bonam matrem habemus_—_i. e._, A good mother we have, or rather (literally) Good mother we have for the Latin strangely has no articles, or none which correspond to our _an_ (_or a_) and _the_, and which may be translated by them.
