Type
Types are a means to split monsters into groups (in a broader way to what Attributes do) in order to enable Support Cards granting various effects, to a specific order of monsters. Players use Field Spell Cards to use Type divides to their advantage.
Each monster has one Type. There are twenty-two different legal Types in the TCG and OCG. Divine-Beast is exclusive to the Egyptian Gods and was considered Illegal, although it is now legal in the OCG and TCG as of January (with the first legal English-print God Card, "Obelisk the Tormentor"). Immortal only appears in Yu-Gi-Oh! The Duelists of the Roses.
When "type" is written with a lowercase "t", it does not refer to this category of monster. It instead refers to the three main types of cards; Monster, Spell or Trap. Those three terms are usually given in brackets after this to avoid confusion. For example "Ordeal of a Traveler".
OCG/TCG
These Types exist within the OCG and TCG.

Overlap with attributes
Many Types tend to be associated with certain Attributes. Types are not listed here if one or two Attributes do not clearly cover a majority of monsters with that Type (for instance, Dragon-Type monsters are fairly evenly divided between three different Attributes, so "Dragon" is not listed here). Types that are listed here are only listed with the Attributes that cover a majority of monsters of that Type.
