Lilliputian is an adjective that means small or petty.
Our word of the day comes from the Jonathan Swift novel Gulliver’s Travels as a reference to a tiny group of people roughly six inches tall. More recently the word may be used as a noun to refer to a small, petty thing or as an adjective. For example: I lost my nail clipper as we were climbing the mountain. But in the midst of such a monumental occurrence, we had no time for such lilliputian concerns.
