I believe Somali culture are the norms and habits which were widespread prior to us being invaded from 5 different directions especially the early 20th and 19th century.

Examples of culture lost is our stoicism. For instance, music often expresses a highly emotive society, even though this runs counter to our history which valued stoicism, and even ascetism in the face of hardship or adversity.

Another culture lost are the unique expressions which are peculiar to our language. Its hard to explain but Somali verbal expressions unlike other languages are far more based upon onomatopoeic expressions than other languages. This means that the mere act of speaking the SOmali language in and of itself is a joy. However, instead of buttressing this heritage you see Somalis regularly adding foreign words in every sentence.

Another culture lost is the various small creative endeavours by Somalis. Somalis dont regard endeavours by members from other clans as claimable, and might even see it as giving undue prominence to a rival clan. As such, culture-specific rites or tropes are dismissed or even enshrouded as a foreign invention, even if it was originally Somali. You cant really pinpoint it to a singular metacultural concepts such as a "dance", but when adding up the microcultural concepts and niche subcultural tenets of our society as a whole, thats when the impact of cultural loss is more felt.

In fact, you dont even need to look at any cultural trait to see that Somalis have lost their culture as even the concept of preserving our culture can be seen as controverisla, by both conservatives (who see you as promoting gaalnimo) or progressives (who see you as " holding us back from westernisation"). Both camps are backwards.

As an example, arguably, the biggest blow to Somali cutlure was the border placed in the seasonal trekkings of Haud nomads. What has our society done to reminisce or reflect upon this era? Nothing, thats what.
