documentation: an vs a

[videlec]

There are many wrong instances of the indefinite article a/an in the doc. eg

arith/misc.py:    -  ``n`` - an nonzero integer
categories/sets_cat.py:               `r` is an homomorphism from `B` to `A` (typically a
...

More delicate : some beginning vowels are not vowel sound, for example y-sound

algebras/quantum_groups/fock_space.py:            Return an unicode art representing the generator indexed by ``m``.
combinat/dyck_word.py:        Return an unicode art representation of this Dyck word.
combinat/posets/hasse_diagram.py:        This lattice has an unique "possible orthocomplement" for every
graphs/base/c_graph.pyx:        The digraph obtained from the ``PetersenGraph`` has an unique strongly
...

Also, most of the words starting with h should be used with a and not an

algebras/commutative_dga.py:            Return the cohomology class of an homogeneous cycle, as an element
categories/complex_reflection_groups.py:    element of `\operatorname{GL}(V)` fixing an hyperplane pointwise
categories/sets_cat.py:               `r` is an homomorphism from `B` to `A` (typically a

(only exceptions are heir, heiress, honest, honour, hour)

Do the above mentioned constitute all of them? Or is it required to search for more?

The examples in the PR issue description are a very small part. I did use git grep to find them. For example

$ git grep '\san\s[bcdfghjklmnpqrstvwxyz]'

give 327 occurrences of doubtful usage of an (some of them being correct as the above also catches an hour which is correct).

Ok I'll see if I can go through all of them

Update: there will be a lot of files in the diff. Also, there are a few more things to consider:

• an followed by words starting with a capital letter e.g a URL instead of an URL
• have to avoid non-english text e.g an sehr (German)
• some articles are not followed by a letter e.g an ``spkg-src``
• there is some jargon with which the choice of article is ambiguous/both can work e.g a ssh connection or an ssh connection
• in case of ambiguities mentioned in the previous point, I will break the tie depending on pronunciation e.g if SSH is pronounced with individual letters, then the suited article will be an but for another word beginning with s like structured graph, a will be appropriate
• there are places where and is misspelt as an e.g this is dubious an may be deprecated Correcting these as well.
