### Difference between a theorem and lemma?

Theorem: A mathematical statement that is proved using
rigorous mathematical reasoning. In a mathematical paper, the term
theorem is often reserved for the most important results.
Lemma: A minor result whose sole purpose is to help in
proving a theorem. It is a stepping stone on the path to prove a
theorem. The distinction is rather arbitrary since one
mathematician's major is another's minor claim. Very occasionally
lemmas can take on a life of their own (Zorn's lemma, Urysohn's
lemma, Burnside's lemma, Sperner's lemma).

### What is the difference between dilemma and lemma?

Dilemma and Lemma are very different concepts.
A lemma is the most basic form of a word, and the usual way one
lists words in the dictionary. For example, of the words "running",
"runner", "ran", et al., the lemma of these would be "run". Unlike
an infinitive, which is the most basic form of a verb, lemmas apply
to every form of word. A related concept to a lemma is "lexeme",
which is not all that different, it is the most basic idea of a
word. A lemma is simply a way of representing a lexeme.
A dilemma (which comes from di-, meaning two, and -lemma,
meaning a premise or idea,) is a strict choice between two
propositions, ideas, outcomes, or something similar. Usually, the
choices within a dilemma are undesirable. For instance, having to
choose between being late for work or helping a friend with an
unpleasant task is a dilemma. If the issue involves three choices,
it is a trilemma; four choices, a tetralemma; five choices, a
pentalemma, and so on. Generally, they are all referred to as
syllogisms.
