Try reading here:
http://mywiki.wooledge.org/Arguments
under the heading:
Parameter Expansions
particularly this sentence:
"""
It is vital to understand, however, that Quoting and Escaping are
considered before parameter expansion happens, while Word
Splitting is performed after.
"""
The essential point being that quoting and escaping occur
before most expansions, and word splitting after.

And then for more detail about the various expansions, there is
this sentence from 'man bash':
"""
The order of expansions is: brace expansion; tilde expansion,
parameter and variable expansion, arithmetic expansion, and command
substitution (done in a left-to-right fashion); word splitting; and
pathname expansion.
"""
