What is a good/standard list of "simple English words" suitable for puzzling?

Question

Suppose I'm trying to computer-solve a puzzle, or computer-create a puzzle, where "every word in the whatever is a common English word." For example, intuitively, BUNNY is a common English word, TAPIR is borderline, and EURYPTERID is definitely not a common English word.

Where would I find a computer-readable wordlist of "common English words" in this sense?

I'm aware of the following resources and their disadvantages:

• The SOWPODS list (e.g. here). Major disadvantage: It contains obscure words such as AALII.

• "Basic English" lists (e.g. here). Major disadvantages: They lack many common words such as MOUSE. They almost always lack declensions, e.g. the linked list contains CAT but not CATS.

• Crossword wordlists (e.g. here). Major disadvantages: They contain abbreviations such as SSGT, multi-word phrases such as ATONCE, and proper nouns such as CYRUS.

• The "Up Goer Five" wordlist, constructed from one of Wiktionary's computer-generated frequency lists plus the Automatically Generated Inflection Database (AGID). Major disadvantages: It lacks many common words such as MOUSE. Because it blindly uses AGID, it includes some surprising declensions, such as CATTED and CATTING.

Answer 1

I found the following additional resource.

• 2of12inf.txt from the 12dicts package.

It successfully contains all of BUNNY TAPIR CAT CATS MOUSE.

It successfully omits all of EURYPTERID AALII SSGT ATONCE CYRUS CATTED CATTING.

UPDATE:

• Minor disadvantage: It contains some short words that I would consider "dubiously English" — COS EM EMS EN ENS HES HI HIS HO HOS MA MAS MENS OM OMS PA PAS PIS RE REC REM and so on.

• Minor disadvantage: It contains some words that IMHO do not pass the breakfast table test — BITCH RAPE SHIT SHAT and so on.

However, I'm still having good luck with this wordlist plus minor manual edits!
