consonant cluster

When I first started to learn English,
I was confused to find that some consonants lie side by side
in a English word without sandwiching a vowel between them.
For example, "s," "p," and "r" lie side by side in "spring."
This scarcely occurs in a Japanese word.

Such a group of consonant sitting side by side is called

"consonant cluster."

They say that Italian language is easy for Japanese people
to pronounce.
I guess one of the reasons is a consonant cluster in an Italian
word is shorter than that in an English word.

In Italian word, sometimes,
a consonant is skipped with staccato rhythm.
And sometimes,

English: n + s + t  (constitution)
Italian: s + t   (costituzione)

English: n + c + t  (instinct)
Italian: n + t   (istinto)

a consonant just disappears without a word.
Sad, though easy...
