* Average: The Greek word for average is μέσος όρος (mésos óros). "Mésos" means middle or average, and "óros" means limit or boundary, but in this context, it signifies the average value.
* Miserly/Stingy: Words like φειδωλός (pheidōlós) or άπληστος (áplēstos) could be used, depending on the nuance. "Pheidōlós" implies carefulness bordering on stinginess, while "áplēstos" means insatiable or greedy, implying stinginess through greed.
* To intend/signify: This could be translated using words like σημαίνει (sēmainei) which means "it signifies" or εννοώ (ennoō) which means "I mean" or "I intend."
* Angry/Ill-tempered: Greek has many words for this depending on the specific type of anger; θυμωμένος (thymōménos) is a common word for angry.
* The middle point (between two things): μέσος (mésos) itself is suitable here.
To give you a proper Greek translation, please clarify the intended meaning of "mean" in your context.
