<!-- EDITORIAL NOTE: Do not add mnemonics here, unless they are particularly illustrative. See "List of mnemonics" article instead -->
A common mnemonic technique for remembering a list is to create an easily remembered [[acronym]]. Another is to create a memorable phrase with words which share the same first letter(s) (i.e.: the same [[initialism]]) as the list members. Mnemonic techniques can be applied to most memorization of novel materials.

Some common examples for first-letter mnemonics:
* Mnemonics for spelling ''mnemonic'' include "memory needs every method of nurturing its capacity" and "maybe not every mnemonic oozes nuisance intensely concentrated".
* To memorize the [[metric prefix]]es after giga, think of the candy, and this mnemonic. "Tangiest [[Pez]]? Yellow!" TPEZY: tera, peta, exa, zetta, yotta.
* The order of [[Sharp (music)|sharps]] in [[key signature]] notation is F, C, G, D, A, E and B, giving the mnemonic "Father Charles goes down and ends battle". The order of [[flat (music)|flats]] is the reverse: B♭, E♭, A♭, D♭, G♭, C♭ and F♭ ("Battle ends and down goes Charles's father").<ref>{{cite book|title=The Quarterly Musical Review|url=https://books.google.com/books?id=KeoqAAAAYAAJ&pg=PA107|volume=1|year=1885|publisher=J. Heywood|page=107}}</ref><!-- This mnemonic is significant for its long history and its reversibility -->
* The colours of the [[rainbow]] in "[[Richard III of England|Richard of York]] gave battle in vain", "Run over your granny because it's violent" or the fictional name "Roy G. Biv" (red, orange, yellow, green, blue, indigo, violet).
* The acronym HOMES for the North American [[Great Lakes]]: Huron, Ontario, Michigan, Erie, and Superior<ref>{{cite web|url=http://www.happychild.org.uk/acc/tpr/mne/1199gtlk.htm|title=Great Lakes Mnemonic – part of the Accelerated Learning Series|website=www.happychild.org.uk}}</ref>
* Electronic colour codes are remembered with [[List of electronic color code mnemonics|a wide range of mnemonic phrases]], owing to multiple colours beginning with ''b'' and ''g'' and shifts from sexist phrases once common in traditionally male-dominated professions.<ref name="Morse_2001">{{Cite book |publisher=Basic Books |isbn=0-7382-0615-6 |page=308 |author-last=Morse |author-first= Mary |title=Women Changing Science: Voices from a Field in Transition |date=2001 |url=https://books.google.com/books?id=veqNOLMfqOIC&q=%22bad+boys+rape+our+young+girls%22&pg=PA44}}</ref>
* For [[Power factor#Mnemonics|effects of an inductor or capacitor]] in [[alternating current]] circuits, the phrase "Eli the iceman" or "Eli on ice" has been used by electrical engineers. With an inductor present (the symbol ''L'' indicating inductance), the peak value of voltage (''E'') precedes the peak value of the current (''I''), so ''E'' precedes ''I'' in "Eli". With a capacitor present (the symbol ''C'' indicating capacitance), the peak current leads the peak voltage, with ''I'' leading ''E'' when ''C'' is present in "ice". Another common mnemonic is "civil": in a capacitor (C) current (I) leads voltage (V), while voltage leads current in a inductor (L).
* For [[redox]] chemical reactions, where oxidation and reduction can be confused, the phrase "Leo says ger" (lose electron oxidation, gain electron reduction) or acronym "oil rig" (oxidation is losing, reduction is gaining) can be used.<ref name="Mnemonic Methods">{{cite book|last=Glynn, Shawn|title=Mnemonic Methods|year=2003|publisher=The Science Teacher|pages=52–55|display-authors=etal|id={{ProQuest|214619949}}}}</ref>
* [[Planetary mnemonic]]s include: "My very educated mother just served us nachos" or "my very easy method just speeds up naming planets" (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, [Pluto]).<ref>{{cite web |url=http://www.iau.org/public_press/news/release/iau0603/questions_answers/ |title=Questions and Answers on Planets |access-date=2008-07-06 |url-status=bot: unknown |archive-url=https://web.archive.org/web/20140208183938/http://www.iau.org/public_press/news/release/iau0603/questions_answers/ |archive-date=February 8, 2014 }}</ref>
