Sort each word — does it take 'a' or 'an' in front of it? (Remember: 'an' goes before a word that STARTS WITH A VOWEL SOUND, even if the spelling starts with a consonant, like 'an hour'.)

Each clue describes a word. Sort the word by which vowel sound it begins with — an A/E sound, or an I/O/U sound. (Clue: toast = a slice of bread; temple = a place of worship; apron = worn while cooking; April = a month; Urdu = a language; igloo = a type of house; orchard = fruit trees growing together; umbrella = used in the rain; elephant = a large grey animal; owl = a bird that hoots at night.)

Fill in the blank with 'a' or 'an'. Write just the missing word.
