A sturdy slab-serif with assertive, square-cut serifs and largely unbracketed joins. Strokes are fairly even overall, with subtle modulation in curves, and terminals resolve into crisp horizontal and vertical ends. Counters are open and clean, with round forms kept steady and symmetrical; the lowercase shows a readable, workmanlike construction with a two-storey “a” and compact “e,” while the numerals are robust and clear. Spacing appears straightforward and consistent, supporting continuous reading in paragraph settings.

Well-suited to book and long-form editorial typography where a strong serif structure helps maintain a consistent text color. It also performs convincingly in headlines, reports, and institutional or product branding that benefits from a sturdy, traditional slab-serif voice.

The overall tone is traditional and dependable, leaning toward an editorial and academic voice. Its firm slabs and crisp geometry give it a confident, no-nonsense presence that feels established rather than playful.

Likely intended as a versatile slab-serif for general typography: strong enough to anchor headlines and titles, yet restrained and regular enough to carry paragraphs with clarity and a confident, established tone.

The design balances rectilinear detailing in the serifs with smooth, rounded bowls, creating a steady rhythm across mixed-case text. Uppercase shapes read solid and upright, while the lowercase keeps a practical, text-forward color that remains composed at larger sizes.
