20. After much research into Waggledagger (Shakespeare) I offer 2 words used as interjections which may be relevant:
fie (interjection): For shame! Nonsense! (Used to express disagreement, annoyance, or mild disgust). Example: "Fie on't! ah fie! 'tis [the world is] an unweeded garden" (Hamlet, 1.2.139).
--------------------------------
pish (interjection): Exclamation of disgust, discontent, or impatience. Example:
BARDOLPH Good lieutenant! good corporal! offer nothing here.
NYM Pish!
PISTOL Pish for thee, Iceland dog! thou prick-eared cur of Iceland! (Henry V, 2.1.17-19).
The first one, fie, might lead us to FIELD, but I cannot account for the LD.
The second one contains references to ice, but I can't see any relevance. Maybe you can, emperor. I shall think on.
