The word 'slaggier' is derived from 'slag' (from Old Norse 'sloggr', meaning waste material from metal smelting) combined with the comparative suffix '-ier' (indicating more). Thus, 'slaggier' refers to something that has more slag or waste material compared to something else.
Think of 'slag' as waste material, and remember that 'slaggier' means having more waste or being more wasteful.
