Igual is primarily an adjective and an adverb.

As an adjective, it has the plural form iguales but does not change for masculine or feminine singular: un resultado igual / una cantidad igual.
As an adverb, it remains unchanged: trabajan igual — “they work in the same way.”
It comes from Latin aequalis, meaning “equal” or “level.”
The common expression igual que means “the same as” or “just as”: igual que tú — “the same as you.”

mismo — “same.” It usually emphasizes identity or sameness, while igual can also mean “equal,” “similar,” or “in the same way.”
idéntico — “identical.” This is stronger than igual and suggests that there is no meaningful difference.
equivalente — “equivalent.” It focuses on having the same value or function, not necessarily looking the same.
parecido — “similar.” This is weaker than igual because it indicates resemblance rather than complete equality.
nivelado — “level” or “even,” when referring to a surface or distribution.

diferente — “different”; the most general opposite of igual.
desigual — “unequal” or “uneven”; the direct opposite when referring to value, treatment, or level.
distinto — “distinct” or “different,” often emphasizing that two things are not the same.
opuesto — “opposite”; stronger than diferente and indicating contrary qualities or positions.
