Template:a or an
![]() | This template uses Lua: |
This template determines whether the first word in the argument provided begins with a vowel or consonant and returns with it "a" or "an" depending on the assessment.
Usage[edit source]
In general, it returns "an" if the first letter is a, e, i, o, or u, and "a" if any other:
"{{a or an|word}}"
→ "a word""{{a or an|elephant}}"
→ "an elephant"
To capitalize "a", wrap the template in {{ucfirst:...}}
.
"{{ucfirst:{{a or an|word}}}}"
→ "A word""{{ucfirst:{{a or an|elephant}}}}"
→ "An elephant"
Words beginning with a vowel letter[edit source]
Words that begin with eu, ew, uni, etc., and others like one, once, and U are exceptions:
"{{a or an|European}}"
→ "a European""{{a or an|one-sided game}}"
→ "a one-sided game""{{a or an|U-turn}}"
→ "a U-turn""{{a or an|Ukrainian}}"
→ "a Ukrainian""{{a or an|university}}"
→ "a university"
Some exceptions are made to the above rule.
"{{a or an|Euler diagram}}"
→ "an Euler diagram""{{a or an|unimportant case}}"
→ "an unimportant case"
Words beginning with a consonant letter[edit source]
Words that begin with a consonant letter also have some exceptions:
"{{a or an|heir}}"
→ "an heir""{{a or an|hour}}"
→ "an hour""{{a or an|honor}}"
→ "an honor""{{a or an|honour}}"
→ "an honour""{{a or an|nth degree}}"
→ "an nth degree""{{a or an|x-ray image}}"
→ "an x-ray image""{{a or an|Xbox}}"
→ "an Xbox""{{a or an|ytterbium fiber}}"
→ "an ytterbium fiber"
Abbreviations[edit source]
Words in all caps are treated as initialisms. If an initialism begins with F, H, L, M, N, R, S, or X, it returns "an". If it begins with U, it returns "a". Thus:
"{{a or an|LED}}"
→ "an LED""{{a or an|led}}"
→ "a led""{{a or an|URL}}"
→ "a URL""{{a or an|url}}"
→ "an url"
Some notable acronyms are made exceptions.
"{{a or an|FIFA referee}}"
→ "a FIFA referee""{{a or an|NASA program}}"
→ "a NASA program"
Numbers[edit source]
If the first word begins with 8, 11, or 18, it returns "an", unless it is read with "hundred", "thousand", etc. at the beginning.
"{{a or an|11}}"
→ "an 11""{{a or an|18th}}"
→ "an 18th""{{a or an|110}}"
→ "a 110""{{a or an|1800}}"
→ "an 1800" (assumes it's a year)"{{a or an|1,800}}"
→ "a 1,800""{{a or an|180,000}}"
→ "a 180,000""{{a or an|180000}}"
→ "a 180000""{{a or an|18,000,000}}"
→ "an 18,000,000""{{a or an|18000000}}"
→ "an 18000000"
Ambiguous cases[edit source]
If |variety=us
is set, herb(s) and herbal are treated as starting with a vowel sound.
"{{a or an|herb}}"
→ "a herb""{{a or an|herb|variety=us}}"
→ "an herb"
Words before which people have not settled on whether to use "a" or "an" are generally not made exceptions, so the general rules apply.
"{{a or an|FAQ}}"
→ "an FAQ""{{a or an|upsilon}}"
→ "an upsilon"
If the first letter is a non-Latin character, it returns "a" by default.
