verschwindend vs erheblich
considerable
'erheblich' and 'verschwindend' both describe how large or important something is. But they are clearly opposites. You use 'erheblich' when a difference, damage, or amount is large and important. 'verschwindend' means that something is extremely small or almost unimportant. 'verschwindend' sounds especially natural in fixed combinations like 'verschwindend gering' (vanishingly small / negligible) or 'verschwindend klein' (vanishingly small). A simple guide is: 'erheblich' means clearly a lot; 'verschwindend gering' means almost nothing.
verschwindend
Das Risiko ist bei dieser Behandlung verschwindend gering.
The risk with this treatment is vanishingly small.
erheblich
Die Reparatur war erheblich teurer als geplant.
