Joseph, to get technical right back, "Affect" has different meanings in the dictionary and each usage is associated with each meaning.
Same is true about "too" which is, technically speaking, "de jure" one word but "de facto" two different words. Which is why you can have "too much" (excessive) or "you too" (also).
Ok, let's blow some minds, folks! Get your breakdowns here!
AN before a vowel such as "an apple" but A before a consonent, as in "a car" unless, specifically, you are using the phrase "an historic occasion" which is the exception. It is also acceptable to say "a historic occasion."
In British English we tend to use AESK to spell certain words of foreign derivation, particularly "haemoglobin" vs. the American "hemoglobin". Same is true with the repeating O in zoology or zoonose where we are apt to set the second and separately pronounced O with a diaresis such as "zoölogy". But while Americans don't use aesk for words of Greek origin, they do for words of Anglo-Saxon origin such as "Æthelred".
You really don't want to do organisations (note spelling) our way because a group may be singular or plural depending upon emphasis. In short, in referring to the ENTITY such as the Red Cross, the Red Cross IS a very old organisation (because it is one thing), but the local branch of the Red Cross ARE meeting at my house (because it is a group of several people). Nobody would have problems with "The Beatles are famous" because "Beatles" is plural with an S on the end, but we would also say the same about the choir..."The Choir are meeting at the church."
Ptth. Need Tylenol yet?
