Grammar Post #5

To or too.. This is something that Mike and I were just arguing about so I decided I'd research what the answer is.

Too is an adverb, and two different meanings give it two different distinct placements.
Too meaning excessively, to an excessive degree...
You worry too much.
Isn’t it just too obvious?
In these cases, the adverb too precedes an adjective.
Too meaning also, in addition.
Mike is coming too!

To is a particle. The infinitive in English consists of two parts: the particle to and the verb. Here are four infinitives:
to giggle to chuckle to snigger to laugh
If you see to before a verb, as above, it’s acting as part of the infinitive. Too never does that.
Gretchen snickered when Hannah said she wanted to order fish and chips.
To climb Mount Everest takes guts.
To used as a particle and too used to modify a following adjective can look deceptively similar:
Edna went to work.
Charles arrived too late. http://www.educationbug.org/a/to-vs--too.html

And yes I am right again :) Sorry Mike..
