[conlang_learners] IE vs non IE

[Arthaey Angosii]

English is my native language and Spanish is the only other language I
can hold a conversation in. So while my artlang Asha'ille is a priori,
I'm "concerned" that it adheres too closely to whatever makes IE
languages look IE.

What are the defining characteristics of an Indo-European language,
con- or natlang? (Apart from shared vocabulary/etymology, of course.)
What grammatical features make a language IE-like? Are those features
found also in non-IE languages?
