An analytic language is a language that conveys grammatical relationships without using inflectional morphemes. A grammatical construction can similarly be called analytic if it uses unbound morphemes, which are separate words, and/or word order. Analytic languages are in contrast to synthetic languages.
A related concept is the isolating language, which is about a low number of morphemes per word, taking into account derivational morphemes as well. A purely isolating language would be analytic by necessity, lacking inflectional morphemes by definition. However, the reverse is not necessarily true: a language can have derivational morphemes while lacking inflectional morphemes. For example, Mandarin has many compound words, giving it a moderately high ratio of morphemes per word, yet since it has almost no inflectional affixes at all to convey grammatical relationships it is a very analytic language.
The term "analytic" is commonly used in a relative rather than an absolute sense. English has lost much of the inflectional morphology of Proto-Indo-European, Proto-Germanic and Old English over the centuries and has not gained any new inflectional morphemes in the meantime, making it more analytic than most Indo-European languages. For example, while Proto-Indo-European had inflections for eight cases in its nouns, English has lost most of them, conserving only the genitive (possessive) -'s.
For comparison, nouns in Russian inflect for at least six cases, most of them descended from Proto-Indo-European cases, whose functions English translates using other strategies like prepositions, verbal voice and word order instead.
However, English is also not totally analytic in its nouns as it does use inflections for number, e.g. "one day, three days; one boy, four boys". Mandarin has, in contrast, no inflections in its nouns at all: compare 一天 yī tiān 'one day', 三天 sān tiān 'three days' (literally "three day"); 一个男孩 yī ge nánhái 'one boy' (lit. "one [entity of] male child"), 四个男孩 sì ge nánhái 'four boys' (lit. "four [entity of] male child").
