Hello Lindsey Star,
The double consonants in Korean equal the specific sounds in the Romance languages.
I speak French but unfortunately not Italian nor Spanish. So my explanation will be based on French.
Unlike English, the Romance languages has got double consonants sound in the Korean language.
ㅃ is exactly the same sound with some words such as 'petit, pas, espagnol, Paris, pardon etc.
The sound is the same when pronounced in the French word.
However, it's different in English. It tends to sound p, ㅍ in Korean because French can agree on my
opinion that native English speakers pronounce Paris as not the French actually do.
ㄲ is the strongest among ㅋ, ㄱ, and ㄲ. The ㄲ sounds just like car, Cartier, kilo, cafe, carme in French.
On the other hand, ㅋ sounds just like English K, or C as in crown, carrier, Kelly, key.
ㄸ is the similar sound in English as in strike, stop, steal, street, stable different from table, treat, top, trick.
In addition, in French it's the same with the Korean language about ㄸ, as in table, tu, tableau, terme
But not the same when pronounced as in tien, triste, travailler, tradition, and so on, cloes to ㅌ rather than
ㄸ in Korean.
I hope it's helpful enough for you to get it.
Lee,
