Exceeding a normal, usual, reasonable, or proper limit.
Synonyms: excessive, immoderate, intemperate, inordinate, extravagant, extreme
These adjectives mean exceeding a normal, usual, reasonable, or proper limit. Excessive has the widest range: excessive drinking; excessive debt. Immoderate and intemperate denote a lack of due moderation or restraint: immoderate political views; intemperate personal remarks. Inordinate adds to these words a sense of going beyond what is proper or deserved: inordinate self-regard; took an inordinate time to reply. Extravagant sometimes specifies lavish or unwise expenditure (extravagant gifts); often it implies overstepping the bounds of reason or prudence (extravagant claims; extravagant speculation in the stock market). Extreme suggests going far beyond what is normal, desirable, or generally acceptable: an extreme diet; an extreme ideology.
