Because OP specifically asked also for Aramaic, I'd like to add some info from Aramaic perspective. In Aramaic the word in use is ܣܓ݂ܶܕ݂ܘ which roughly means
[they] worshipped / adored / paid homage to [someone]
This is according to Aramaic/Syriac dictionaries. There is no "greeting" there.
Is "worship" an appropriate translation for this word? Is greeting a
possible translation? Is this particular word ever translated as
greeting?
Worship seems to be quite appropriate and sufficent, but I would allow other interpretations too. Especially that the other meaning of ܣܓ݂ܶܕ݂ܘ is "paid homage" and in some languages and cultures "to greet someone" has very similar meaning to "to pay homage". Even more - sometimes greeting is actually like paying homage. In my native language (Polish) word cześć is translated as casual English hi but actually it literally means be honored. And oddawać cześć is translated as "worship" while it can also mean "pay homage"! There is some connection between these meanings. For me, it is very clear that ܣܓ݂ܶܕ݂ܘ and its inflections can also have meaning of greetings and salutations apart from its main meaning of worship and paying homage.
Some example verses from KJV (in which I mark in bold appropriate word from Peshitta) illustrating that sometimes worship could be changed to greetings:
Mark 15:19 And they smote him on the head with a reed, and did spit
upon him, and bowing their knees worshipped him.
For me this is about Roman Soldiers saluting Jesus as Jewish king (just like they would salute Casear), not worshipping him like a God.
Matthew 2:11 And when they were come into the house, they saw the
young child with Mary his mother, and fell down, and worshipped him:
and when they had opened their treasures, they presented unto him
gifts; gold, and frankincense, and myrrh.
Matthew 8:2 And, behold, there came a leper and worshipped him,
saying, Lord, if thou wilt, thou canst make me clean.
Matthew 9:18 While he spake these things unto them, behold, there came
a certain ruler, and worshipped him, saying, My daughter is even now
dead: but come and lay thy hand upon her, and she shall live.
Matthew 18:26 The servant therefore fell down, and worshipped him,
saying, Lord, have patience with me, and I will pay thee all.
Mark 5:6 But when he saw Jesus afar off, he ran and worshipped him,
Acts 10:25 And as Peter was coming in, Cornelius met him, and fell
down at his feet, and worshipped him.
And there are some more verses, but I don't see a need to list everything.
