The Irish Culture is widely known around the world as a very friendly, sociable culture. From the very start of their culture when Ireland was inhabited by the Celts, expressions of emotions were very important, almost more important than they are today. Emotional Expressions would have been a very big part of how people communicated how they felt and what they wanted, as well as what they liked and disliked. In those times actions would speak a lot louder than words, and so how you expressed what you were feeling was majorly important, and very significant to how these expressions would have been comprehended by the people who were receiving them. Specific actions were used for specific emotions, and would always be closely related to this emotion whenever they were seen.
The Earliest Irish settlers would greatly reply on their body language to aid them to express their emotions, as speech would have not been descriptive enough for what they are willing to express. |Body language such as a raised fist to show anger, or sometimes even a hug or embrace to show love and happiness would have been very commonly used, rather than speaking and expression words that way.
As time has gone on from early Celtic settlers to modern day habitats emotional expressions of the Irish has greatly changed and is now more reliant of speech and the power that words will have to express how you fell rather than the excessive amount of body language that would have been used then. This is due to the evolution of language but also other factors such as learning respect and how to behave, which influences emotional expression greatly.
The language used by the Irish to express these emotions is also very unique to many of the other cultures, as they develop sayings and words that can easily express what they are feeling. "Slan" is an Irish word meaning good health, which can be used to express happiness and kindness. They have many of these sayings, some of which can be viewed here, http://www.sampleireland.com/famous-irish-sayings.html.
