Ambivium is a modification of the nice Junction font, designed by Caroline Hadilaksono of The League of Moveable Type.
All glyphs in the Light, Regular and Bold weigths have been ‘cleaned-up’, by: adding missing extrema, correcting self-intersecting paths, rounding non-integral point coordinates.
Text (‘old-style’) numerals of the standard Junction fonts have been restored into the web fonts and made the default in all fonts.
Small caps have been added to the regular weight.
“Ambivium” is a (not very common) Latin word roughly equivalent to “junction”, at least in its meaning of crossroad.
