The second declension masculine* endings are:
singular:
nominative: -er, -ir, -us
genitive: -ī
dative: -ō
accusative: -um
ablative: -ō
plural:
nominative: -ī
genitive: -ōrum
dative: -īs
accusative: -ōs
ablative: -īs
Words in -ir add the oblique endings directly to the nominative form (vir -> virī); some words in -er drop the -e- before adding oblique endings (magister -> magistrī), while some don't (puer -> puerī). Words in -ius often form the genitive singular in -ī (not -iī).
Words in -us form the vocative singular in -e; words in -ius form the vocative singular in -ī. In all other cases the the vocative is identical with the nominative.
Deus has some irregular forms, including nominative plurals dī and diī in addition to deī.
(*Strictly speaking, these are not masculine endings, but non-neuter ones. There is a small group of feminine 2nd-declension nouns in -us, mostly the names of trees, islands and cities, that are declined in exactly the same way.)
In the 3rd declension, you have the masculine, feminine, and neuter nouns. They each have their own sets of endings. The nominative, however, is unpredictable. Here is a chart:

There are many masculine singular endings in Latin, depending on the part of speech (noun, adjective or pronoun) and the case (how the word is used in the sentence). Most of these endings are not specific to masculine words.
Probably the set of endings with the best claim to being "masculine singular endings" are the singular endings used for masculine adjectives of the second declension. These are:
The third declension does not have a distinct set of feminine endings. The only gender-specific endings in this declension are for the neuter gender.
The non-neuter 3rd declension endings are:
Singular:
Plural:
The genitive plural form is -ium for adjectives and so-called i-stem nouns; -um otherwise. A very few nouns appear with an accusative singular in -im instead of -em (e.g. vim "force"; turrim alongside turrem "tower"). Adjectives also take ablative -irather than -e, as do a few i-stem nouns (vi; turri alongside turre).
The second declension vocative ending for the masculine singular is '-e'. For the masculine plural and neuter singular and plural, the vocative ending is the same as the nominative ending.
Latin words in the first declension are generally feminine. The nominative singular usually consists of the stem with the ending -a, with the genitive ending in -ae.
The perfect tense endings in Latin are:
I - i
You - isti
He/She/It - it
We - imus
You (plural - istis
They - erant
Example: Amo, To Love
Singular Plural
Amo Amamus
Amas Amatus
Amat Amant
The second declension vocative ending for the masculine singular is '-e'. For the masculine plural and neuter singular and plural, the vocative ending is the same as the nominative ending.
um a i orum o is um a o is
Tempus is a neuter noun of the third declension. Its genitive is temporis.The complete declension is:Singularnom./voc. tempusgen. temporisdat. temporīacc. temporemabl. temporePluralnom./voc. temporagen. temporumdat. temporibusacc. temporaabl. temporibus
The 3rd declension masculine endings in Latin typically include -is in the genitive singular, -i in the dative singular, -em in the accusative singular, and -es in the nominative and accusative plural.
WARD in Latin is Defendo in first declension. fendere in second declension. fendi in third, and fensum in fourth.
The third is the declension of the Latin word vēritās. The feminine, third declension noun in its singular nominative or vocative form translates as "truth" in English. The pronunciation will be "WEY-ree-TAS" in Church and classical Latin.
The Latin for "word" is verbum, a second declension neuter.
Paeninsulis is either the dative plural or the ablative plural of paeninsula, -ae, f., "peninsula". The full declension is:SingularNominative/vocative: paeninsulaGenitive: paeninsulaeDative: paeninsulaeAccusative: paeninsulamAblative: paeninsulaPluralNominative/vocative: paeninsulaeGenitive: paeninsularumDative: paeninsulisAccusative: paeninsulasAblative: paeninsulis
If you are asking about the vocative, or "calling" case, it is used by inflected languages for direct address. In Latin, for example, the word lord is dominus for the nominative subject of the verb, as in Dominus vobiscum ( the lord is with you ), and domine for the vocative of address, as in Non nobis, Domine ( not to us, O Lord). The different endings on the words do for Latin what word-order does for English, which is to show who does what to whom.

The Latin word for "war" is bellum, which is a second declension neuter.
