IBAR

'Ibar' is a Basque word and a linguistic root ('i')'bar' meaning 'valley'.
It explains many place names as:

★ Ibarra, Ebro < Iberia, Ibra (Germany)…
and words characteristic of the Aquitano-Iberic area as:

★ ''barro'' 'mud',

★ ''barranco'' 'torrent', 'gully',

★ ''barta'' 'damp plain'.
The Basque words:

★ barren, barne 'lower place',

★ ibai 'river' < ''ibarre'',
and the linguistic root:

★ barka 'lower place'
are related.
This root should not be mistaken for the root barr- 'wooded relief'.
