Why is English grammar so simple?

English grammar might seem simpler compared to some other languages, but it's not entirely devoid of complexity. Its simplicity in certain aspects might be due to historical influences. Over time, English has undergone significant changes, shedding a lot of its inflectional grammar that many other languages, like German or Latin, still possess.

English grammar is considered simple for a few reasons: 

Word order and prepositions: English uses these to convey meaning, making it easier for learners to construct sentences.

Spelling: English is easier to spell than most languages.

Pronunciation: English has easy sounds for foreigners to pronounce, like "th", "ae", and "w".

Conjugations: English doesn't have too many conjugations. Verbs don't change because of the pronouns, but it is necessary to add the “s” or “es” at the end of the third person.

Rules: English grammar rules are relatively flexible.

English grammar is often perceived as relatively simple compared to some other languages for a few reasons:

Lack of Gender and Case: English nouns do not have grammatical gender like many other languages (e.g., French, Spanish, German), and there are limited cases (nominative, accusative, genitive, dative) compared to languages like Latin or Russian.

Fewer Verb Forms: English verbs have relatively few conjugation forms compared to languages like Spanish or French, where verbs change according to tense, mood, aspect, person, and number.

Simplified Word Order: English typically follows a subject-verb-object word order, making sentence structure more straightforward compared to languages with more flexible or rigid word orders.

Fewer Inflections: English has reduced inflectional morphology compared to many other Indo-European languages. For example, English adjectives generally do not change according to the gender, number, or case of the noun they modify.
