More than enough; excessively: She worries too much.
To a regrettable degree: My error was all too apparent.
Very; extremely; immensely: He's only too willing to be of service.
Informal Indeed; so: You will too do it!
[Middle English to, from Old English tō, to, furthermore; see de- in Indo-European roots.]
Usage Note: Some language critics have objected to the use of not too as an equivalent of not very, as in She was not too pleased with the results. In many contexts this construction is entirely idiomatic and should pass without notice: It wasn't too long ago that deregulation was being hailed as the savior of the savings and loan industry. It was not too bright of them to build in an area where rock slides occur. In these cases not too adds a note of ironic understatement. · Negation of too by can't may sometimes lead to ambiguities, as in You can't check your child's temperature too often, which may mean either that the temperature should be checked only occasionally or that it should be checked as frequently as possible. · Too meaning "in addition" or "also" is sometimes used to introduce a sentence: There has been a cutback in federal subsidies. Too, rates have been increasing. There is nothing grammatically wrong with this usage, but some critics consider it awkward.
"in addition, in excess," late O.E., stressed variant of O.E. prep. to "in the direction of, furthermore" (see to). The spelling with -oo is first recorded 1590. Use after a verb, for emphasis (e.g. did, too!) is attested from 1914. Ger. zu unites the senses of Eng. to and too. Slang too-too "excessive in social elegance" first recorded 1881. Too much "excellent" first recorded 1937 in jazz slang.
Al"so\, adv. & conj. [All + so. OE. al so, AS. ealsw[=a], alsw?, [ae]lsw[ae]; eal, al, [ae]l, all + sw[=a] so. See All, So, As.]1. In like manner; likewise. [Obs.] 2. In addition; besides; as well; further; too. Lay up for yourselves treasures in heaven . . . for where your treasure is, there will your heart be also. --Matt. vi. 20. 3. Even as; as; so. [Obs.] --Chaucer. Syn: Also, Likewise, Too. Usage: These words are used by way of transition, in leaving one thought and passing to another. Also is the widest term. It denotes that what follows is all so, or entirely like that which preceded, or may be affirmed with the same truth; as, "If you were there, I was there also;" "If our situation has some discomforts, it has also many sources of enjoyment." Too is simply less formal and pointed than also; it marks the transition with a lighter touch; as, "I was there too;" "a courtier yet a patriot too." --Pope. Likewise denotes literally "in like manner," and hence has been thought by some to be more specific than also. "It implies," says Whately, "some connection or agreement between the words it unites. We may say, ` He is a poet, and likewise a musician; ' but we should not say, ` He is a prince, and likewise a musician,' because there is no natural connection between these qualities." This distinction, however, is often disregarded.
