Gender
In the Spanish language nouns are either masculine or feminine. Some groups of words can be identified by gender, however it's best to learn the word with its correct article due to some exceptions.

Masculine	Singular	Plural
Definite Article	el	los
Indefinite Article	un	unos

Masculine words are normally defined as: nouns ending in -o, -r, -n, and -l; names of items in nature; days of the week and months; words of Greek origin ending in -ma, -pa, or -ta.

Feminine	Singular	Plural
Definite Article	la	las
Indefinite Article	una	unas

Feminine words are normally defined as: nouns ending in -a, -dad, -tad, -tud, -cion, -sion, -ez, -umbre and -ie; names of towns and cities.

Negation
When stating a negative comment or phrase in Spanish, simply ad the word no before the verb or pronoun.
For example: I do not like it. No me gusto.
                      I don't have anything. No tengo nada.

Verb Conjugation
Verbs in the Spanish language infer the subject person by their endings.
For example one can say: Yo hablo Español. Or simply: Hablo Español.
The -o ending in hablo (form of hablar, meaning to speak) infers that it is in the first person. The following table illustrates the common rules of verb conjugation.
