Usage tips
Context clue
The meaning of 'ur' depends on its position in the sentence. As a prefix before a noun (e.g. 'Urwald' — primeval forest), it means 'original' or 'ancient'. If it stands as its own word before an adjective (e.g. 'ur gut'), it is colloquial for 'very'.
EXAMPLE
Die Urgroßeltern meiner Frau kamen aus Polen.
My wife's great-grandparents came from Poland.
Word formation as a prefix
In its original meaning, 'ur-' is a prefix that is attached directly to a noun to form a new word. It is not declined like a normal adjective and never stands alone.
EXAMPLE
Der Ursprung des Konflikts liegt viele Jahre zurück.
The origin of the conflict lies many years in the past.
Typical combinations
The prefix 'ur-' forms many fixed terms. Common examples are 'Urwald' (primeval forest), 'Ursprung' (origin), 'Urzeit' (prehistoric times), 'Urmensch' (early human), or kinship terms such as 'Urgroßeltern' (great-grandparents).
EXAMPLE

ur vs sehr
very
'sehr' and 'ur' can both intensify a quality. 'sehr' is the normal and neutral form that you can use everywhere. In this use, 'ur' means something like 'very' or 'totally', but it is colloquial and is common mainly in Austria and in some regions of Germany. That is why 'ur gut' (really good) sounds completely normal to some speakers, but regional or very informal to others. If you want to speak safely and neutrally, 'sehr' is the better choice.
ur
Der Ausflug ist ur schön, weil wir direkt am See sind.

sehr
Beim Termin hören wir sehr genau zu, weil das Thema wichtig ist.
During the appointment, we listen very carefully because the topic is important.
