الفرق بين بعض الكلمات التى يصعب احيانا تحديد الفرق بينها بسهولة

Historic and historical
In one sense these words are distinguished from each other, but in another sense they overlap.
Historic, according to The Cambridge Guide to English Usage (p. 250):
is more self-consciously associated with the making of history, so that a historic event is one which people feel is particularly significant in the life and culture of the nation. Historical is more neutral, acknowledging that something belongs to the past, or to the study of the past, or else that it really happened and is not fictitious.

According to this usage, a historical book is a book about history, but a historic book is one that is particularly significant in the culture, perhaps because it was the first of its kind — the first novel, the first book printed rather than copied by hand, the first book to deal with a certain subject, etc.

A historical person is one who really existed in the past. Legends are usually fantastic imaginary stories that grow around a historical figure. That is, the person really existed, even though the deeds and events of the legend are imaginary or exaggerated.

Similarly, a historical event is one that actually happened, though it may not be significant. A historic event, on the other hand, is one that is significant.

According to The Cambridge Guide, a historical building is simply an old building. A historic building is considered important because a memorable event happened in or near it — an assassination, the signing of a treaty, the founding of an important organization, etc.

However, references disagree on whether historic can mean "very old". The Longman Dictionary of Contemporary English and the Merriam-Webster Collegiate Dictionary give one meaning of historic as "very old" or "dating from or preserved from a past time or culture." This meaning is also common on the Internet.

Electric and electrical

Corpus evidence shows that electric is the more common word. We tend to use electric when referring to a specific thing that is powered by electricity or produced by electricity: electric train, electric drill, electric current, electric shock, electric fence, electric car.

We use electrical for more generic terms or for words that relate generally to the nature of electricity: electrical appliances, electrical equipment, electrical energy, electrical engineer.
