Etymology of samurai
The word samurai has its origins in the pre-Heian period Japan when it was pronounced saburai, meaning servant or attendant. It was not until the early modern period, namely the Azuchi-Momoyama period and early Edo period of the late 16th and early 17th centuries that the word saburai became substituted with samurai. However, by then, the meaning had already long before changed.During the era of the rule of the samurai, the earlier term yumitori (弓取り) was also used as an honorary title of an accomplished warrior even when swordsmanship had become more important.Kyujutsu (弓術)/ Japanese Archer, is still strongly associated with the war god Hachiman (八万).

invaders. Any leader with a supply of superior weapons was at a great
advantage, so a constant, long-term effort to find swordmakers improving
the craft ensued. The most devoted smiths made the quest for the
perfect blade into a lifetime pursuit, and men exist today who devote
their lives to the art of swordmaking.
Consequently, swordsmiths developed forging techniques to make a curved
blade at least as strong as the earlier straight ones. These swords,
called tachi, were extremely long, some nearly four feet, and were
generally used by soldiers on horseback. The long, curved blade was
ideal for a sweeping draw and slash against opponents on the ground or
mounted upon other horses.
