One little trick I learned along the way regarding the verbs "lie" and "lay" (in the
Present Tense) :
1. If the word RECLINE would substitute, use LIE (e.g. I will lie/recline on the sofa.) ;
2. If the word PLACE would substitute, use LAY (e.g. I will lay/place the book on the shelf.).
This works in most instances for distinguishing one from another.
P.S. A pet peeve of mine is the use of IMPACT. Standing alone, it is a noun. As a verb, "upon" or "on" should follow.
Examples: NOUN - The impact of the news left many folks stunned.
VERB - The weather will impact upon our decision of whether or not to postpone the picnic.
WRONG (IMHO): The weather impacted the cancellation of the picnic.
I don't doubt that one day IRREGARDLESS will become "acceptable."
