<p><b>New page</b></p><div>A '''lemma''' is a [[theorem]] used to simplify the proof of some other theorem. One might draw an analogy to the use of components in the construction of an electronic device -- no electronic device really "needs" separate components, but [[modular design]] greatly simplifies and stabilises.<br />
<br />
When giving a lemma a name, one might say that the lemma is "towards" a given theorem. Then, when proving the main theorem, one might say "by the lemma" to draw on the result of the latter.<br />
