lettuce is letxati

letxati = lettuce (noun) (some things Google found for "letxati": a nearly unique term; similar lekhati or lekxati means "now, right now, just now, a short time" in the extinct Biloxi Native American language; a bad OCR of the word legati in a medieval Latin book)

Word derivation for "lettuce":
Basque = letxu (Spanish is lechuga)
Finnish = lehtisalaatti (lehti = leaf, newspaper; salaatti = salad)
Miresua = letxati

With a word for lettuce, I end this string of vegetable words.

cabbage is azki

azki = cabbage (noun) (some things Google found for "azki": an uncommon term; user names; Al Azki and Azki are rare last names; Azki's Designs jewelry shop on Etsy; Azki Performance Exhaust / Azki Doctor Muffler of Indonesia sells motorcycle exhaust pipes; Azki (aka Izki) is the name of a place in Oman)

Word derivation for "cabbage":
Basque = aza, Finnish = kaali
Miresua = azki

I considered making this word akza, but that word would've contained all the letters from the Basque word, which is something I'd rather not do. Also I'm trying, not that successfully, to lessen the number of nouns ending in a.

potato is patuna

patuna = potato (noun) (some things Google found for "patuna": an uncommon term; Patuna Bushyhead is a female couture designer originally from the Republic of Georgia; Patuna Farm Adventures and Patuna Chasm near Martinborough in New Zealand; a rare last name; a rare feminine first name; Vadiga Patuna is a traditional Southern Sri Lanka dance; in Finnish an essive form of the noun patu which means "(colloquial) old hand"; Yapa Patuna is a former name of Jaffna, Sri Lanka)

Word derivation for "potato":

Miresua = patuna

This is a word for Thanksgiving. Our dinner included mashed potatoes.

I considered making this word perata, but that means to gut (a fish) in Finnish.

beet is juremitxa

juremitxa = beet (noun) (some things Google found for "juremitxa": a rare term; user name on YouTube; similarly named Jurimex Law Firm of Ukraine; similarly named Jurimex provides legal assistance toll free in collaboration with the Consulate General of Mexico in Miami)

Word derivation for "beet":

Finnish = juurikas (also punajuurikas, where puna means red)
Miresua = juremitxa

Here's another lengthy vegetable word. As in Finnish, the j is pronounced like consonantal y. As in Basque, the tx is pronounced like ch.

I'm a gardener and I grow vegetables, including beets.

This Miresua conlang word has been changed. The word for beet is now jurmotxas.

Miresua = naurbi

Yes, I know that making a word for turnip isn't exactly advancing Miresua grammar. Sorry, but I've been busy lately. Doing vegetables is allowing me to maintain my blog update schedule.

carrot is azporena

azporena = carrot (noun) (some things Google found for "azporena": an unique term, did not match any documents; similar Azorerna is the Swedish name for the Azores which is a Portuguese autonomous archipelago located in the Atlantic Ocean)

Word derivation for "carrot":

Miresua = azporena

This is second in my series of long words for orange vegetables. Both Basque and Finnish have 8-letter words for carrot, so Miresua does too.

This Miresua conlang word has been changed. The word for carrot is now azporano.

pumpkin is kurpaza

kurpaza = pumpkin (noun) (some things Google found for "kurpaza": a rare term; a user name; "kurpa za" can mean "cloth or towel for" in Bulgarian (transliterated); similarly named Kapaza is a Belgian classified ads site)

Word derivation for "pumpkin":

Here's another Halloween inspired word.

sugar is zokre

zokre = sugar (noun) (some things Google found for "zokre": an uncommon term; name of a Mexican professional wrestler who is half of the Los Luchas tag team; user names; name of a couple of World of Warcraft characters; a rare first name)

Word derivation for "free" (gratis, without charge):
Basque = dohako, Finnish = ilmainen
Miresua = dolain

I made this word start with D, which is unusual in Miresua. In Finnish only borrowed words start in D. It turned out to be unintentionally similar to the Basque word dohain (which is related to dohako), the noun for a spiritual, intangible gift.

far is kaurun

kaurun = far (far away) (adverb) (some things Google found for "kaurun": a rare term; user names; Asuweda Kaurun ho is a Sinhala song title (which I was unable to translate to English); a rare last name; name of a village in Himachal Pradesh, India)

Word derivation for "far":

The adjective far will be a similar word, but with an additional suffix.

Word derivation for "near":
Basque = hurbil, Finnish = lähellä

The Finnish word lähellä is adessive case, which a locative case with the basic meaning of "on". I don't think Basque has adessive case.

Other words for near in Basque are gertu and ondoan.
