If you know C:
'abc'    |"abc"
$a       |'a'

If you know some philosophy:

compare the relations:
is a kind of
is a part of
compare sets in set theoretical and mereological meaning
(in mereological meaning {a}=a)

If you know some linguistics:
compare count nouns with mass nouns

half of a car isn't a car
half litre of water is water

is a character a string?
in Smalltalk the answer is NO.
