as well. A purely isolating language would be analytic by necessity and lack inflectional morphemes by definition. However, the reverse is not necessarily true, and a language can have derivational morphemes but lack inflectional morphemes. For example, Mandarin Chinese has many compound words, giving it a moderately high ratio of morphemes per word, but since it has almost no inflectional affixes at all to convey grammatical relationships, it is a very analytic language. English is not totally analytic in its nouns since it does use inflections for number (e.g., "one day, three days; one boy, four boys") and possession ("The boy's ball" vs. "The boy has a ball"). Mandarin Chinese, in contrast, has no inflections on its nouns: compare 'one day', 'three days' (literally 'three day'); 'one boy' (lit. 'one [entity of] male child'), 'four boys' (lit. 'four [entity of] male child'). Instead, English is considered to be weakly inflected, and comparatively more analytic than most other Indo-European languages. Persian could be considered an analytic language. Generally, there are no inflections as we know it. There is a system of prefixes and suffixes which are used to connect the words to express possession or attribute a quality. They could be integrated in the word in writing while keeping their function. For example, the suffix makes the words plural like does 's' in English. Therefore, 'The girls came'. In Persian, the is no agreement of subject's (or adjective's) number (or gender in many other languages because of being inherently a Genderless language)). Practically, there are no inflections for numbers keeping the above example; 'one day', 'three days' (literally 'three day'), 'one boy' (lit. 'One boy'), 'four boys' (lit. 'Four boy'). Similarly, there are no inflections for possession as well. A short '-e' sound (a diacritical mark) added after a word starting with a consonants letter, shows that it is possessed by (or belongs to) the next word so 'The boy's ball' would be . However, this diacritical mark 'ـِ' is put under the last letter of the first word for beginners and in written literatures and everyday publications it is usually omitted but is pronounced when reading. For the words ending to long vowels a letter is added with short '-e' sound written as as suffix so 'The boy's foot' would be . However, in literature and daily writings it is omitted but pronounced in reading. The same system is used
