Fill in the blank with the suitable article: I borrowed ___ pencil from your…

Correct answer: 'a'

Explanation: Use 'a' before a singular, countable noun that begins with a consonant sound. The word 'pencil' begins with the consonant sound /p/, so 'a pencil' correctly indicates one non-specific pencil taken from the pile.

• Why not 'an': 'An' is used before words starting with a vowel sound (for example, 'an apple' or 'an hour'). 'Pencil' does not begin with a vowel sound.

• Why not no article: Singular countable nouns generally require an article or determiner. Omitting the article is only correct for plurals or uncountable nouns (for example, 'pencils are on the table').

• Why not 'the': 'The' refers to a specific, known item (for example, 'the pencil you gave me'). The sentence refers to any one pencil from the pile, so the indefinite article is appropriate.

Short examples:

• I borrowed a pencil from your pile.

• I need an eraser.

• Pencils are on the table.
