Above: The Dual NDVI Ultra Probe Unit is powered by a Nano Logger (enhanced by an array of beryllium spheres) and is ready for field action. The TSL2561 is a common luminosity sensor. It measures how bright it is and reports in units that relate to the brightness that people perceive (lux).
An adjective describes (tells us more about) a noun or a pronoun. For example: student is a noun. But we can say more about the student in our sentence by using an adjective: intelligent student; clever student; lazy student; good student... etc. So, here is a sentence: The teacher says Marie is a good student.
In linguistics, an adjective is a describing word, the main syntactic role of which is to qualify a noun or noun phrase, giving more information about the object signified. Adjectives are one of the English parts of speech, although historically they were classed together with the nouns.or example, rather than an adjective meaning big, a language might have a verb that means to be big, and could then use an attributive verb construction analogous to big-being house to express what English expresses as big house.
