Template documentation[view] [edit] [history] [purge]

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[स्रोत सम्पादन]

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[स्रोत सम्पादन]

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[स्रोत सम्पादन]

Words that begin with a consonant letter also have some exceptions:

  • "{{a or an|heir}}" → "an heir"

  • "{{a or an|honour}}" → "an honour"

  • "{{a or an|Xbox}}" → "an Xbox"
  • "{{a or an|ytterbium fiber}}" → "an ytterbium fiber"

Abbreviations[स्रोत सम्पादन]

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|NASA program}}" → "a NASA program"

Numbers[स्रोत सम्पादन]

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[स्रोत सम्पादन]

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.

  • "{{a or an|あ}}" → "a あ"

If the parameter is not entered, it returns an empty string.

  • "{{a or an}}" → ""
