The phrase "in the grain" is spelled exactly how it sounds in English. The "in" is pronounced as "ɪn" with the short "i" sound, and "the" is pronounced as "ði" with the voiced "th" sound.

"In the grain" is a phrase that can have literal and figurative meanings, depending on the context in which it is used.
In its literal sense, "in the grain" refers to the direction of the fibers or lines that naturally occur in the wood of a tree. The grain of the wood runs parallel to the tree's trunk and branches, and it can be seen as a pattern visible on the surface of cut wood. When a piece of wood is cut "against the grain," it means that the cut is made perpendicular to the natural direction of the fibers. In contrast, if a cut is made "in the grain," it means that the cut follows the natural direction of the fibers.
In a figurative sense, "in the grain" can refer to something being deeply embedded or ingrained in a person's character, habits, or mindset. It suggests that certain qualities, beliefs, or behaviors are inherent and intrinsic to someone's nature, rather than being imposed from external influences. For example, if a person is described as being generous in the grain, it means their tendency to be generous is an innate part of who they are, rather than a result of external influences.
Overall, "in the grain" can refer to the natural direction of the fibers in wood or to something deeply ingrained in someone's character or nature.
