Singular nouns take singular verbs, just as a plural noun attracts a plural verb: The problem in identifying whether a noun or a verb is plural or not is whether or not "s" or "es" should be added to the noun or verb. To make a noun plural, add "s", "ies", or "e". Examples: singular nouns: animal, man, irregularity. Their plural forms: animals, men, irregularities. While plural nouns take "s", "ies", or "e", plural verbs do not. Plural nouns and plural verbs in sentences: The men(plural noun) hate(plural verb) her. The irregularities(plural noun) do(plural verb) not say much... The animals(plural noun) do(plural verb) rest a lot. To make a noun singular, do not add any letter like "s", "ies", or "e". Singular nouns: boy, irregularity, man. To make a verb singular, add "s," "ies", or "es". Singular verbs: takes, does. Singular nouns and singular verbs in sentences: (1) The boy(singular noun) sings(singular verb) well. (2) The irregularity(singular noun) exemplifies(singular verb) the chaos. (3) The situation(singular noun) does(singular verb) not scare me.

Pronoun/antecedent agreement which states that a pronoun must refer to only one antecedent clearly in gender and number: a pronoun is a word used instead of a noun while an antecedent is the word that a pronoun refers to or replaces. Pronoun example: Tola is a good girl. She is very kind. "She" is a pronoun for replacing "Tola". The antecedent of the pronoun "she" is also "Tola" as this is what the pronoun replaces. In this example, the pronoun "she" replaces the noun/antecedent "Tola" properly in terms of gender as Tola is a girl and "she" is a female pronoun. The pronoun "she" also refers properly to the noun/antecedent "Tola" in terms of number as "Tola" is one person(singular) and "she" is also singular. Another example: The diatribes(plural) are unprecedented as they(plural) are considered the first. It is wrong to say "the diatribes(plural) are unprecedented as it(singular) is considered the first.

A bit of idioms: Considered as or to be is wrong. So, it is wrong to say "women are considered as better homekeepers". You should say "women are considered better homekeepers". It is wrong to say regarded to be. So, only say "women are regarded as better homekeepers".

A word that begins with a vowel sound must attract the "an" article. For example: I have an egg. A word beginning with a consonant sound must attract the "a" article. Example: The room is a hell.

After using the "a" article, do not use a plural noun. Do not say "I have a beautiful sisters". You should say "I have a beautiful sister" or "I have beautiful sisters".
