Cześć

Shamrock to trójlistna koniczyna (zwykle chodzi tutaj o koniczynę drobnogłówkową lub białą), a clover to po prostu koniczyna. Dodatkowo, "shamrock" to symbol Irlandii. Nie określa się go raczej nazwą "clover", chyba że wyjaśniając czym jest "shamrock".

Hi tlstar- na podstawie informacji z "Wikipedia" , nazwa "shamrock" pochodzi z Irlandii,

A shamrock is a young sprig, used as a symbol of Ireland. Saint Patrick, Ireland's patron saint, is said to have used it as a metaphor for the Christian Holy Trinity.[1] The name shamrock comes from Irish seamróg [ˈʃamˠɾˠoːɡ], which is the diminutive of the Irish word for plant (seamair) and means simply "little plant" or "young plant".[2]

Koniczyna- informacja podaje iż koniczyna bywa trójlistna, niemniej jednak pojawiają się roślinki wielolistne i jest podany oficjalny "Guinness World Record of 18 lucky.",
Clover, link- https://en.wikipedia.org/wiki/Clover
Clover or trefoil are common names for plants of the genus Trifolium (Latin, tres "three" + folium "leaf"), consisting of about 300 species of plants in the leguminous pea family Fabaceae. A group of clovers is called a cluff.
Clovers occasionally have four leaflets, instead of the usual three. These four-leaf clovers, like other rarities, are considered Guinness World Record of 18lucky. Clovers can also have five, six, or more leaflets, but these are rarer. The record for most leaflets is 56, set on 10 May 2009.[6] This beat the "21-leaf clover",[7] a record set in June 2008 by the same discoverer, who had also held the prior .[8]

A common idiom is "to be (or to live) in clover", meaning to live a carefree life of ease, comfort, or prosperity.
Pozdrawiam.
