Scald, skald or skald, n. an ancient scandanavian bard.

Scald / Skald, an ancient Scandinavian bard who recited or sang at feasts compositions in honour of chiefs and famous men and their deeds. This word represents the Icelandic Skãld, Danish Skald, Swedish Skjald, the regular term for a poet. Authorities differ as to it’s derivation. It seems certain that the word was originally derogatory in sense. Some connect it with Skãlda, a pole, on which libels were cut. Others, for example Skeat, refer it to the swedish Skjalla, to make a loud noise or clatter, and take the original sense to have been a "loud talker." This would link the word with "Scold", to rail at, find fault with, which is formed from the Dutch Sc / bid, past tense of Scheldan, cf.German Schelten, in the same sense.

Scald / Skald, from old Norse Skald, poet, "satirist."
Scold, from middle English scolde, an abusive person. Combined bard and warrior.They sang songs in combat to psyche up the troops for attack. Most Scald songs are categorised as chants. This means you can only have one going at a time and most of them will stay active until cancelled or until a new song is played. Notice that most Scald songs was stated, as this is not the case for all songs (an example would be direct damage songs).

They are honoured and respected members of their clans. Every war party loves to have a Scald in it’s midst. This assures that their great deeds and mighty skills will be honoured in the Scalds next recital, and thereafter immortalized for all time. Members of bands treat Scalds with the utmost respect and courtesy. It is well known that the foolish warrior who maligns Scald will soon hear his name slandered in innumerable ballads across the land. As previously stated, by chanting a war song, a Scald can inspire allies during combat. This chanting can elevate spirits, remove concerns about danger, keep men’s minds focused on combat and keep friendly forces with a sense of being larger than life. They love all legends about war and have a myriad of construction techniques available to them. The Scaldic tradition is often encoded with the use of metaphors.

Of different origin is the verb "Scald," to burn or injure the skin or flesh by hot liquid or steam. Also to cleanse an object, or to remove hair or bristles by exposure to moist heat. This word is derived from the old French Escalder, Eschauder, modern Échauder, Latin Excaldare.
