Adding the suffix -al to a word does not change its stress. ( khi thêm hậu tố -al vào từ không làm thay đổi cách nhấn âm của từ. )EX: music /'mju:zik/ musical /'mju:zikl/Note: If a word can take both suffixes: one ending in -ic and the other ending in -al, both words have the stress on the same syllable.(Nếu một từ có thể dùng cả hai hậu tố : một hậu tố là - ic và một hậu tố khác là - al thì giữa hai từ này có cách nhấn âm.) EX: economy /i'kɒnəmi/ economic /,i:kə'nɒmik/ economical /,i:kə'nɒmikl/: kinh tế 5.
