t we are warm; we say "We feel _warmly_ on
this subject," when we mean that our feeling is warm. "As a rule, it is
proper to use an adjective whenever some form of the verb 'to be' or 'to
seem' may be substituted for the verb, an adverb when no such substitution
can be made."[113] Thus, "He looked _angry_; he spoke _angrily_." Sometimes
we may use either adjective or adverb with no difference in meaning: as,
"We were sitting _quiet_ (_quietly_) round the fire."

Regarding the _form_ of adverbs, ill-taught pupils often suppose that all
words ending in "-ly" are adverbs, and that all adverbs end in "-ly." A
glance at the italicized words in the following expressions will remove
this delusion: "Come _here_;" "_very_ pretty;" "he _then_ rose;" "lay it
_lengthwise_;" "he fell _backward_;" "run _fast_;" "_now_ it is done;" "a
_friendly_ Indian;" "a buzzing _fly_." Though no comprehensive rule can be
given for the form of adverbs, which must be learned for the most part by
observation, it may be helpful to know that most "adjectives of quality,"
like _gentle, true,_ take the suffix "-ly" to make a corresponding adverb;
and that the comparative and superlative degrees of adverbs ending in
"-ly" usually prefix _more_ and _most_.
