Can you use the -ly suffix with any noun? e.g "Hotelly" [closed]

I think it's possible that you've confused the suffixes -ly and -y in this case.

As Hot Licks mentioned, -ly is mainly used in English to turn an adjective into an adverb: for example, the adjective cold + -ly = the adverb coldly. The adverb-forming suffix -ly is not attached to nouns.

There are some adjectives that are formed from nouns + -ly, such as friendly, daily, manly, kingly, godly, homely, sisterly, but this is not a common structure for newly formed adjectives.

Newly formed adjectives that are derived from nouns are more likely to use -ish (as Francis and Xanne mentioned) or -y. I would interpret "hotelly" as hotel + -y, with the double ll being the result of the spelling rule about doubling consonant letters in certain contexts before vowel-initial suffixes (compare sun and sunny). This use of -y doesn't have any strong restrictions that I know of, but it is informal and not a very frequent device. Examples of hotelly being used:

• "not annoyed by very hotelly hotel prices" -- The Spectator, August 13, 1892

• "Did I miss some shortcut here, do you think this is an element of creating a very hotelly feeling or something like that or is this waste of my time just bad game design?" -- "the lift in the hotel", Thimbleweed Park discussion on Steam, May 21 2017

For comparison: I think the analogous adjective for "apartment" would be apartmenty, not apartmently. See these examples:

• "I would read the reviews of the entire complex to decide. They are very apartmenty, close together, no views, many people live there full time." https://www.tripadvisor.com/ShowTopic-g60626-i828-k8026548-Princeville_Condo_Rental_anyone_stayed_here-Princeville_Kauai_Hawaii.html

• "We recently moved from the area where we had been for 20 years ... always loved it although it has become very "apartmenty" and the population has expanded" https://www.tripadvisor.com/ShowTopic-g255068-i461-k12757150-Moving_to_Brissi_where_to_live-Brisbane_Brisbane_Region_Queensland.html

New or "nonce" formations with "y" are sometimes enclosed in quotation marks, as in that last example, or are written with a hyphen between the base and suffix (like "hotel-y" or "apartment-y").

"-ly" is a suffix that is commonly used to turn an adjective (eg, "quick") into an adverb ("quickly"), as in "He quickly decided to quit while he was ahead".

It is sometimes used informally to turn a noun into an adjective (as in your example of "hotel" -> "hotelly"), but that is not a standard technique in English. As Xanne suggests, "-ish" is a better choice.
