Now according to the explanation of the Scottish clan, ,
Now let's see the entry to the armigerous clan, it says
An armigerous clan is a Scottish clan, family or name which is registered with the Court of the Lord Lyon and once had a chief who bore undifferenced arms, but does not have a chief currently recognized as such by Lyon Court.
And as I made a comment to Mark C Wallace, English speakers don't distinguish correctly between the name of "clan" and "family" at all.
In reference to Takeda clan ( in my sense it should be Takeda family ),
The Takeda clan (武田氏 Takeda-shi) was a Japanese clan active from the late Heian period until the late 16th century.
and it also says
In this Japanese name, the family name is Takeda.
I am getting totally perplexed. Do native speakers or historians fully understand the difference of these 2 terms?
Side note : Japanese families were or did just perish if they lost their "chief" and Japanese Samurai system had no armigerous clan system like the above mentioned Wiki and were not regulated by the Court Lyon, the public body, the Samurai families in Japan made their pledge to a family, the Biggest and Mightiest family among them ( If it was Hojo the de facto Shognate, or Ashikaga Shogunate or Tokugawa Shogunate ( they were all family too. They had a chief, even though how old they they were ( even the "chief" was 4 r 5 years old. ) and together with the members of the biggest family made their laws and regulations and economic and religious policy. The family without its chief was unthinkable. I think it would be completely different from the Scottish clan. ( But yer some choose to use the word "clan". )
Can anybody clarify furthermore the difference between these 2 terms so that later on they are going to be used properly?
Thank you for your assistance in advance.
