I am looking for a word which might be used to describe the unnecessary and lavish expenditure of money.

I seem to recall this particular word roughly being the opposite of 'frugal'.

An example sentence might be; "The Decor of Sir Wilfred's house pointed to a _____ lifestyle"

  • @FumbleFingers 'profligate' was the first to come to mind, but it wasn't in thesaurus.com's list. As great as that site is, I am often disappointed that what I think is the exact match is sometimes just not even on their list. I think that has more to say about the complexity of English vocab than the site. – Mitch Dec 11 '18 at 14:05
  • @Mitch: Yeah - I had "profligate" in mind when I followed your link in the first place. So I couldn't help noticing that I actually had to type it (as opposed to my usual labour-saving cut&paste approach) - but I couldn't be bothered to find a different link to a page that really did list it, so I just repeated yours anyway! :) – FumbleFingers Dec 11 '18 at 14:57
  • As a reminder, questions on Stack Exchange should demonstrate some initial research effort, such as checking a thesaurus for antonyms of frugal. I do encourage you to take the site tour and review the help center for additional guidance on writing strong questions. – choster Dec 11 '18 at 15:15


adj a. Extravagant; recklessly wasteful of one's property or means.

For what little of the mixed hardwood stands had survived..at the end of the seventeenth century had been laid waste by greedy and prodigal princelings.



Adjective: spending large amounts of money without thinking of the future, in a way that is not wise:

There have been rumours that he has been prodigal with company funds.

Although the meaning is a clear antonym for 'frugal', there may be an argument that it's being most commonly used in association with 'son' in reference to the parable of the prodigal son, creates a certain potential for confusion over the meaning in some quarters with people thinking it is to with returning after an absence rather than being spendthrift.

  • Ah yes, you have triggered my memory. The example sentence was slightly misleading, but the word I was looking for was Prodigality – William Dec 11 '18 at 14:00
  • I do seem to have a knack of helping you light upon the words you have mislaid! – Spagirl Dec 11 '18 at 14:03
  • What would I do without you! Rest assured, there will be more to come – William Dec 11 '18 at 14:09

I'd use profligate, as per the Google response:

recklessly extravagant or wasteful in the use of resources.

a person who spends improvidently or wastefully

This is the first word that ever comes to my mind for the needs of this question. The word is in general use.

Extravagant works well in this context, I think. From the OED, 'Exceeding the bounds of economy or necessity in expenditure, mode of living, etc.; profuse, prodigal, wasteful.'

Opulent, perhaps:

Rich, wealthy, affluent; ostentatiously luxurious or grand, sumptuous (OED)

| improve this answer | |

I see only one adjective: luxurious  : characterized by opulence, sumptuousness, or rich abundance : of, relating to, or marked by luxury. For example: luxurious accommodations (From Merriam-Webster Dictionary)

Consider squandering, the present participle of the verb 'to squander':

to spend extravagantly or foolishly

(source: Merriam Webster)

extravagant itself would work as well, I guess.
