Must

“Must” bir modal’dır. Bu sebep ile modal kurallarına uygun hareket eder ve kendisinden sonra fiilin ilk halini alır. “Must”, “Have to” ile kıyaslandığında, daha az zorunluluk bildiren bir modal’dır. Must ile kurulan cümleler, konuşan veya cümleyi kuran kişinin hissettiği zorunluluk olarak düşünülebilir.

EXAMPLE

I must sleep now.
She must run fast.
You must love me!

Have to

“Have to” ile cümle kurduğumuzda, kurduğumuz cümle oldukça ciddi bir zorunluluk bildirir. Genelikle, başkasının direttiği ya da yaptırımı olan olaylardan bahsederken kullanılır. “Have to” ile “Must” arasında, bazı durumlarda, net bir çizgi yoktur. Anlatıcının ne anlatmak istediğine göre her ikisi de kullanılabilir.

"Have to" tam olarak bir modal değildir. Cümleler olumsuz olduğunda, olumsuz olan kendini olmaz. Diğer zamanlara göre çekildiğinde, zamanın yardımcı fiili ile çekilir. Aynı zamada kendi de diğer zamanlarda değişebilir.

I had to sacrifice myself or else they could have died.

Olumsuz Olarak Kullanımları

“Must” ve “Have to” modal’larının olumsuz yapıları biraz farklılık gösterir. “Must” kelimesi olumsuz olduğunda, olumlu halinden biraz farklı olarak, artık daha güçlü bir hal alır ve “Have to” gibi davranır. “Have to” olumsuz olduğunda ise “gerek yok” anlamı taşır ve anlamı daha hafifler.

"Have to" aslında bir modal değildir. "Have" fiili, cümle içindeki asıl fiil olarak kullanılır. Fakat biz öğretmenler, öğretilmesi kolay olsun ve anlaşılsın diye modal olarak gösteriyoruz.
