«Same», should not be used as a pronoun: e.g., _Your letter received, and in reply [to same] would say_. Omit bracketed words
«Same as», should not be used for _just as_ or _in the same way_: e.g., _Treat him the same_ [just] _as you would wish to be treated_
«Sensible of», means “having perception”; _sensitive to_ means “affected by”
«Set», should not be confused with _sit_. _To set_ means “to cause to sit”: e.g., _The bird sits upon the tree_, and _The waiter set two chairs for us_
«Sewage», means the contents of sewers; _sewerage_ means the system
«Shall», signifies simple expectancy in the first person, and _will_ represents determination. This reverses with the second and third persons: e.g., EXPECTANCY, I shall (should), thou wilt (wouldst), he will (would), we shall (should), you will (would), they will (would). DETERMINATION, I will (would), thou shalt (shouldst), he shall (should), we will (would), you shall (should), they shall (should). This time-honored illustration of the misuse of these words is easily remembered: _I will drown, nobody shall save me_. In interrogative sentences, the forms of the future are the same as in a declarative sentence, and their proper use may be easily remembered by noting that the same auxiliary is used as is expected in the reply: e.g., _Shall you go?_ suggests merely future action, anticipating the reply, _I shall_ or _I shall not_; _Will you go?_ shows that the speaker expects a reply of determination, _I will_ or _I will not_
«Should», ought not to be used for _to_: e.g., _I want you should_ [to] _do this_. (See also «Want».) As between _should_ and _would_, see «Shall». The same usage obtains, except that sometimes _should_ is used in the sense of _ought_: e.g., _He should be here now_; and _would_ sometimes signifies habitual action: e.g., _Whenever the name was mentioned he would speak slightingly of him_
«Show», should not be used for _play_: e.g., _I went to a show last evening_; nor in the sense of _chance_: e.g., _He has an excellent show of winning_
«Show up», is a vulgarism when used for _expose_
«Since», should not be used for _ago_. Say, _How long ago_ rather than _How long since_
«Size up», is a vulgarism when used for _estimate_
