Upekkha,
From Vatthasutta (The Simile of the Cloth) MN. 7

SC 3.2:
And what are the corruptions of the mind? Katame ca, bhikkhave, cittassa upakkilesā?
…..envy, stinginess, ….. issā cittassa upakkileso, macchariyaṃ cittassa upakkileso
So two words are given to make the distinction, though the translation ‘stinginess’ does not convey the much greater evil inherent in ‘jealousy’
SC 4.12 – 4 15:
‘issā cittassa upakkileso’ti—iti viditvā issaṃ cittassa upakkilesaṃ pajahati;
macchariyaṃ cittassa upakkileso’ti—iti viditvā macchariyaṃ cittassa
upakkilesaṃ pajahati;
ISSA would here then stand for envy and MACCARIYA for jealousy.
wisdomlib.org has :
Factor 9 – Issa (envy): When one hears about or meets an individual superior to one in beauty, wealth, education or morality one often feels envious. This unwholesome thought is issa (envy).
accesstoinsight.org/tipitaka/mn/mn.007 gives:
3…(7) envy…(8) jealousy; scrolling down to the Notes:
7. issa, envy
8. macchariya, jealousy, or avarice; selfishness;
Even given all that, one must still make allowance for the fact that nowadays people say ‘I am jealous (of him)’ when they are in fact envious of him . Afterthought:…. no one ever says ‘I am envious (of my wife/gf)’ when they are jealous of her.
Metta to all
