Similarly after indefinite singulars like _each_, _every_, _somebody_, _anybody_, use the masculine singular pronoun. Thus, _Everyone should do his duty and he should do it every day_. Here one is not only to avoid the use of _he or she_ and _his or her_, but also particularly and constantly to be on guard against _they_ and _their_. Sentences like _Nobody knows what they can do till they try_; _Everyone is urged to come and bring their pocketbooks with them_, are frequently heard and often get into print.
Do not use _the same_ for a third personal or a demonstrative pronoun. _The farmer brought a load of wheat to town and sold it_ (not _the same_) _at the mill_.
Do not make _such_ a pronoun, except in the phrase _such as_. _He has fruits of all sorts and his prices for such are unreasonable_, is the sort of use to be avoided.
Distinguish between _its_, possessive pronoun, and _it's_, contraction of _it is_.
Use _either_ or _neither_ only of two, _any one_ or _none_ of more than two, as: _In one group are Russia, Germany and Austria, in another France and England. Any one of the first group acting with either of the second could determine the question_. (As conjunctions, _either_ and _neither_ may introduce the first of a series of particulars consisting of three or more. It is correct to say _Neither this nor that nor the other thing_; but when used as pronouns, _either_ and _neither_ should be rigidly confined to use with reference to two only.)
Prefer always _no one_ and _nobody_ to _not any one_ or _not anybody_, as _It is no one's_ (or _nobody's_) _business_, not, _It is not any one's_ (or _not anybody's_) _business_.
Do not use _apiece_ for _each_ of persons. Say: _The men each took an apple_ or _took an apple each_, not _The men took an apple apiece_. But they might have bought the apples at so much _apiece_.
Be careful not to say _these sort of things_, _these kind of men_, for _this sort of things_ or _this kind of men_.
In questions direct or indirect be careful to use _whom_ when the objective case is required. Do not say, _Who did you see there?_ or, _I do not know who he meant_.
The relative _who_ should be used only of persons (or of beasts or things personified). Do not say: _The dog whom you saw_ or _He drove the horse who made the best record_. The relative _which_ should be used only of beasts and inanimate objects. Do not say: _The women and children which were numerous then came trooping in_.
