Inputs

word

a string

Outputs

article

"a", "an", or "the"

Word description
Output the proper article given the plurality and first letter of the input. Unlike a/an this word handles plural inputs by outputting the definite "the". If the input is singular as determined by singular? this word operates like a/an.

Notes

•	English lacks a plural indefinite article, so the plural definite is used here instead.
•	This word attempts to preserve the letter case style of the input.
•	Due to the unique way in which the English language is structured, the number 0 is considered plural; 1 is the only singular quantity.
