Fantasai meant that the hyphenation dictionary would not mark the position
after 'a' in 'a-ppend' as a possible hyphenation point.

Dictionary or rule-based hyphenation algorithms would never make that position
breakable and so, no hyphenation would occur.

word-wrap: hyphenate

is telling the user agent to apply sensible hyphenation rules if required to
fit the lines of text. There is no implied requirement to break words at the
end of line if such a break would read badly.

Dictionaries are only one way hyphenation is performed, and in rule based
systems you'd find that breaking after a vowel at the start of a word is
forbidden in English at least.

P.S. The monks that came up with hyphenation hundreds of years ago would be rolling
in their graves right now at the suggestion they didn't understand linguistic
