English Parts of Speech

Determiners were included under adjectives in traditional grammar, however, in modern grammar, determiners are a separate word class, not part of the classic eight parts of speech, but equally important. There are seven types of determiners in the English Language. In older or school-level grammar, determiners (like the, a, this, some, every) were grouped under adjectives because they come before nouns and modify them. 

Following are the tips to quickly identify the part of speech of a word:

• Words ending in -ly are often adverbs such as quickly, commonly, absolutely, etc.
• If a word can be replaced and the sentence still makes sense, it's likely a pronoun.
• If adding “do” can make sense around it, it's likely a verb.
• Removing a word without breaking the sentence generally means it's an adjective.

Yes, one word in English can belogn to more than one part of speech. A single word can function as more than one part of speech, depending on how it's used in a sentence.

For example:

• I run every morning. (Verb)
• I went for a run. (Noun)

• I will work late today. (Verb)
• I am on my way to work. (Noun)

Parts of Speech in English Grammar are very important as they help in constructing grammatically correct sentences which also make sense. They help in improving writing, speaking skills and also help the students prepare for any competitive, entrance or school-level exams. 

Parts of speech is an important topic in exams such as CAT, IELTS, IPMAT, SSC, etc.
